[Q]Whitelevels and screen sharpness

I have only seen 4 galaxy tab 7.7's so far and I noticed all 4 of them really have bad white levels as compared to my galaxy note, disabled the auto power saving and there is a difference in white levels but its still not even close to the galaxy note at the same brightness level. Even at brightness 25% on the note the vs 100% on the tab 7.7shows 'dimmer'whites. This is not a rant but I'm just asking if the screens are calibrated that way or should I keep looking?
Also I noticed that the mdine engine oon the tab provides oversharpening to a lot of my photos and its so obvious and makes the images look bd, supercurio has the same findings.

It is a pretty big screen so it may be they limited the brightnes to save battery power. While the claim is that OLED takes less power than LCD that is not always true. When displaying white, OLED tech uses like 4X as much power as LCD. The power saving comes in when displaying images with medium to darker colors.
What is the "mdine engine"? Is this something that can be bypassed by using a different picture viewing app?
It is amazing how Samsung seems to always add some crappy image "enhancement" like DnIE or such crap. Why can't they just leave our images alone, as we meant them to be? It is freakin' OLED man. You don't need any contrast or sharpness enhancement you knuckleheads! OLED by nature is sharp and has great contrast! Duh!

I don't know. My 7.7 is super bright, sharp and with way warmer colors than my Note.

I'm thinking the samr thing that samsung might ne limiting how bright the whites can go duebto the screen size but based on what I've seen on samoleds some screens juat put out better white levels, not really brighter but whiter.
For the mdine its running system wide.

The samoled plus tends to have more warmer colors than the samoled, is the whites on your tab 7.7 'whiter' than on the note at the same brightness level?

Yes I believe so, Supercurio knows more about that stuff.
EDIT:
simulated example done in photoshop, anyone with the tab7.7 and better photoshop skills feel free to redo this simulated image

Perhaps one of the other reason that the 7.7's screen isn't quite as bright, apart from the obvious power saving reasons, is an effort to possibly reduce the OLED degradation (burn-in) effect.
Either way, although I certainly noticed out of the box that my 7.7 wasn't as bright as my Note (or even my GS2 for that matter!), I was never really bothered by it because (especially when you use movie mode) the colour reproduction is very accurate, and paired up with the contrast levels, it's still fantastic!
I guess, to me, white doesn't necessarily mean I need to put on a pair of sunglasses while looking at my screen lol!

I just wanted to know if the norm has lower white levels, what bothers me more is added sharpening on some images.

I havent but id imagine thats gonna give a yellowish cast on the entire screen. I didnt get the tab yet as the store units I tried had very obvious screen problems. Gonna wait for a the next batch to arrive.

Yellowish? Not at all! At least not with my unit anyway. Sure it makes the screen generally warmer in colour, but IMO, more than anything, it makes the colours look more accurate and natural.
Give it a try! You never know until you do...

Well ever since the Galaxy S changing the color mode to movie mode gives a yellowish cast, this is probably dependent on the calibration on the screen we get in the first place. I saw a friend's Tab7.7 the other day and his white levels were really brighter than my Galaxy Note. FWIW, its still a luck of the draw when it comes to color calibration on the screen. But thanks for that tip, when I'll purchase the Tab I'll make sure to also check out movie mode and see if it hits my requirements.

Very bright noticed the same with the Note ,
Nexus was somewhat easier on the eyes at night,
But probably like you I like a very dim screen at night.
When the brightness is turned all the way down on the 7.7,
is any banding or other issues seen like many report on the Note?
Blacks are black I'm sure but how are greys that are near black.
On the Nexus they were fine, but on the Notes I seen they could have been darker?

Screen Mode is a JOKE

i am wondering what Samsung was thinking
when made of this.
Natural mode has washed out colors and normal mode
has over saturated colors .
We need something between.Is that so difficult?

ur thead is a joke

There are no oversaturated colors
All AMOLEDs are like this and I think display is very good.

Natural mode is pretty much perfect imo.

Totally disagree, natural looks washed out and very dull. My iPad 3 and Galaxy Nexus is much more vibrant.
To me standard, looks fine. Just a touch too over staturated but I like it, like that.

great joke im laughing

Coming from an WVGA TFT LCD on the HD2, the Natural Mode on the SGS3 seems to highlight the best of both worlds.

Standard mode is over saturated especially in games
and when browsing.
An extra mode between standard and natural would be
ideal for 99% of people.

They should just release all phones with a screen calibration mode after the first boot up.
People fail to realize that humans only see about 10 million colours so that the 16 million available, regardless of screen technology, is all there natural or not. There could be a variety of factors that contribute to AMOLED looking less natural but if I were to hazard a guess.
- people are used to seeing LCD looking colours.
- the LEDS are closer to the screen on AMOLED.
- Complete blacks trick our eyes into seeing colours around the black abyss as being brighter than they really are.
And of course the obvious such as a coloured organic Light source vs a white light source plus colour filter. And also the backlight needed on LCDs.
I think consumers just have to be desensitized to AMOLED displays and it will start to look natural. Or Samsung should do a better job with the natural mode and mimic LCD better. Or they should just give free reign of colour calibration like they do on HDTVs and add a back light. So if you like AMOLED, turn off the backlight. If you don't, leave it on. Barring the texture of the LCD colour filter, an AMOLED display with a backlight would look just like an IPS LCD display.

You know what is a joke? All the US versions don't even have a screen mode option. Oversaturation is nothing new for AMOLEDs but it can be remedied and has been remedied before, simply by providing an option. A lot of people like the contrast and viewing angles of AMOLEDs but don't like the excessive colors. I guess Samsung thinks Americans are all colorblind and took the extra effort to REMOVE the option altogether when they tried so hard to make everything else the same. The international S2 had color adjustments too, but not my T-mobile one. Then there's the terrible audio capture. Always taking two steps forward, one step back.

I quite like having an option to change my screen settings rather than not having an option. Thank you Samsung.

I agree as well that screen modes could be better "optimised" that sammy would give us something between natural and standard, but different to you i am feeling that was step in right direction, im sure that next phone will have those much better optimised.

Due to the chipsets. Samsung used the television engine. The screen modes on my international SGS3 is the same ones as on my TV, producing nearly same effects (TV=LCD, SGS3=AMOLED). Sony uses their Bravia engine in their phones.

Hey guys, you do realise people are entitled to an opinion, right? Stop dismissing the OP blindly.
I happen to agree that the default profiles are not as good as they could be. Simply accepting that AMOLED is oversaturated by nature doesn't mean something can't be done about it in software. So before jumping down someone's throat, perhaps consider that they may have a legitimate concern.

Anybody NOT happy with the display?

To the Community:
I just yesterday picked this puppy up at BB and, quite honestly, am very disappointed in the display, specifically the hue. All the yellows are washed out -- WTF???!!
Resolution is awesome but the white background when browsing looks like I'm looking at it under old-style fluorescent lighting -- YUCK!
I've played with all the Settings > Display > Screen mode modes and there's barely a change when going from one to another.
Is this correctible? Is it a TouchWiz thing? Will a different ROM help?
(FWIW -- I'm upgrading from a Xoom running Eos ROMs and other than the resolution, it was gorgeous. The Xoom was a great device: heavy, granted, but the bezel width really did set the standard that tablet manufacturers seem to be migrating towards.)
PLEASE TELL ME THERE'S A SOLUTION!!! THE COLOR RENDITION IS SO UNPALATABLE I VERY WELL MIGHT RETURN IT AFTER LUSTING AFTER IT FOR MONTHS!
Thanks.

Sounds like a hardware problem. I don't see how Touchwiz (or any ROM) could be responsible for that. Better have it exchanged.

Color accuracy is pretty decent on the Note 10.1’s display. As always I’m reporting color data using Samsung’s Movie mode, which remains the most accurate setting of those offered. Grayscale performance is excellent, but our GMB and saturations tests put the Note 10.1 on par with the original Nexus 7. It’s definitely a better calibrated display than any other Samsung Galaxy Note tablet we’ve reviewed. Not quite on par with the new Nexus 7, but getting very close.

My (AMOLED) N3 displaying the same yellow background as my N10.1-14...
My "whites"...

The screen on this amazing and nothing short of that.

You must have a bad tablet...
My screen is great.
I have minor light bleed on bottom edge but thats not bothersome and barely noticeable.
Never had any problems with color rendition. Not to the extent you said it sounds like. Its been pretty natural looking for me.
EDIT: Removed link, its posted two above this...
I dont know what these numbers mean but here is a comparison against a crapple ipad: http://www.phonearena.com/reviews/Samsung-Galaxy-Note-10.1-2014-vs-Apple-iPad-4_id3445

Don't get me wrong, I like the screen a lot. But it is not perfect. I think the pentile design shows when certain colors are next to each other (producing less than perfect transition from one color to another).

No, there's no yellow cast: rather, the yellow's are washed out and not at all vibrant. White backgrounds have a blue-ish gray-ish tone and the only analogy I can muster is that it's like the color temperature is "cool," as opposed to "warm." Canary yellows come out looking dull gold; skin tones are very off-putting and for a top-dollar device, it's really not pleasant.
Side-by-side with my GN2, the colors are much truer on my GN2, hands down.

I leave both my N3 and N10.1-14 on Adapt Display. On the N3 it's the only way to achieve maximum brightness in bright conditions; like an additional 150 nits. I'm not sure if the N10.1-14's Adapt Display works the same way. I have to confess, while Movie Mode may be more accurate I've come to like overly saturated colors on my mobile devices.

To me......... In your (photo 3) side by side photo's I think the device on the left is to red and has to much color saturation the tablet looks good to me in that photo....
There is at lease 2 places in the control panel of the P-600 to adjust color, have you seen them?
If you not happy with the way it looks and you can exchange it you should. If you don't you will always have this thought in the back of your mind.
.

as another user said, it sounds like reading mode is turned on make sure it's off. It probably unlikely that this is the problem though since the the only app that defaults with reading mode on is play books.

Thank you for your responses.
I'm not quite sure how to say this without sounding impolite but several of you seem not to have read my posts completely, so please allow me to start over.
My yellows are very washed out: what ought to be bright canary yellows are dull gold. For example: the yellow in the Chrome logo is what I define as "yellow." On the GM10.1, 2014 Ed. it appears gold and dull.
Skin tones are wan and blue-ish.
White web page areas are gray-blue-ish.
Overall color temperature is "cool."
Reading mode does warm things up a bit...but still, I can't get any combination of settings where yellows "pop".
Settings > Device > Display > Screen mode is set to "movie" and that barely affects the vibrancy of the yellows; in fact there is no real difference between all four of the options.
IN SUM: COLOR RENDITION SUCKS.
Take it back to Best Buy?
(I s'pose I just answered my question...)
Thanks in advance.

The subpixel arrangement creates a dot effect more seen in print when looking through a magnifying glass. While not overly distracting, I do notice it at times. My biggest complaint is the blueish hue shift in darker tones when putting the display at an angle. Is this a TN panel ? I've always had OLED and my Oppo Find 5 was the first smartphone I've owned that didn't have a OLED screen. Still, the find 5 screen was MUCH better than the note 10.1 2014. Especially the black levels are kinda disappointing. I think the screen is WAY overrated in reviews. I primarily use the note in darker indoor areas so I have no use for the extra brightness delivered by the white subpixel.
I still think it's a great device tough, and for the price there is nothing like it. I would like to see some CM and Omni builds for it though which retain the wacom S pen "drivers". I don't care for the samsung features, I just want to use Autodesk Sketchbook.

Overall, I'm really happy with my display. My one complaint is that viewing angles seem to be a little off.

What I know is that this device comes with LCD display. Not amoled. So there.is not pentile design. Because it is not amoled. The color would not look as vivid as amoled, yellow will look like a bit washout because of the backlight compared to amoled

As you can see, Note 10.1 2014 edition is pentile. You can also see this when looking at the screen. Transitions between some colors are a bit blurry.

When talking about display performance there's the objective and subjective. GSMArena, AnandTech, and NoteBookCheck DE all run an extensive battery of standardized tests on all the devices they review. All praise the N10.1-14's display; especially compared to previous Samsung LCD displays.

As for the subjective, assuming those not digging the display don't have a h/w issue, to each their own. The N5's display objectively produces very accurate colors. Those I've seen look washed out and dull. OP's not happy with the coolness of his display. I personally detest warm displays. You can't argue the subjective because it's both personal and opinion.

Nexus 6P display overexposing bright colors in default AMOLED mode

Colors are over exposed
Red appears more like orange, blue like more navy blue, normal orange appears more like saffron.
This happened suddenly and does not get fixed even when I did a Factory Reset.
Phone is 2 weeks old.

Try sRGB mode in developer options. Compare it with another phone if you can. Colors are oversaturated but they shouldn't be "wrong" per se.

I would say that colors are GROSSLY over saturated. Which probably explains why so many think that the camera is great.. Most people would think that over saturation is the next best thing since sliced bread if you put the phone next to the actual scene and the colors were patently different.
As long as I am *****ing about the camera, I was recently doing some panos and discovered tons of stitching artifacts. The Nexus camera does a far better job than the iPhone in controlling exposure than the iPhone, which simply locks the exposure based on the first frame. But the parallax correction on the Nexus is piss poor with obvious misalignment artifacts at every stitch is many scenes. The iPhone in contrast handles the stitching far more elegantly.

Color saturation & accuracy

If you're colorblind, please disregard this thread. Rate this thread to express how you deem the color saturation and accuracy of the Samsung Galaxy Note 8's display. A higher rating indicates that you think that color accuracy is very high and saturation is excellent.
Then, drop a comment if you have anything to add!

1 star . My one is very yellow
Adaptive advanced red off green off blue max
And it is almost white
Might have to return ?

I have the unlocked version, I won't give it a number, but I feel the phone's screen is very good.

Generally very pleased. But Basic mode on display still is very saturated . Also since when was warm a pink hue? Ive always led to believe warm is short wavelength that should exhibit a yellow hue which mine doesn't.

I would like to know the settings for best accuracy since I'd like to edit photos on this, I read the screen has an excellent accuracy but mine is pretty yellowish. Tried the basic mode but its absolutely lifeless and lacks contrast.

Hello. Home theater enthusiast here. Thought I would share my opinion as I have my own calibration tools (i1d3 with HCFR, Lightspace and DisplayCal, and eeColor boxes for 3D LUTs for 1080p and lower content (4K boxes are still too expensive IMO).
This is by far the best display I own. This thing is just as good as my LG E6 OLED... with a 3D LUT! I'd like to mention that the E6 and similar displays are deployed and used for critical grading of movies due to their accuracy and gamut coverage. Without a 3D LUT they're pretty crappy due to limited and buggy built-in calibration controls (you can only have part of the gamut accurate by sacrificing accuracy everywhere else. Skin tones, memory colors or a distributed error focusing on improving the 50-70% saturated colors, can only have one of these or none at all.
Sorry, getting off topic, back to the Note 8 display.
This is very important. DON'T USE ADAPTIVE MODE IF YOU WANT ACCURATE COLORS -OR- THE STANDARD D65 WHITE POINT COLOR TEMPERATURE.
Adaptive has a fairly aggressive boost to saturation. Also, the RGB slider controls are for controlling the SECOND saturation boost on top of what Adaptive has already boosted!
Adaptive/Cinema/Photo use a DCI-P3 in BT.2020 colorspace
Basic uses rec.709/sRGB colorspace.
All non-HDR content (movies, pictures, graphics) do not use this color space. The colors will not be converted properly (primaries and secondaries have an axis shift. Also, 50% saturation in sRGB/rec.709 (non-HDR movies) will be at a different location in the visible spectrum (i.e. not the same color). This is a notable difference if you can quickly do an A/B comparison.
Basic is the most accurate colorspace simply because it's rec.709/sRGB and that is what everything was made for. Use Cinema or Photo if you want/like the saturation boost that happens when viewing /rec.709/sRGB content with a DCI-P3 in bt.2020 colorspace.
HDR videos have embedded metadata (sort of like ID3 tags for music files) which will trigger the display to automatically change to the appropriate and totally separate color space that you can't choose in the display options. The reason for this is because HDR by spec needs each pixel of the screen to produce drastically higher luminance (nits). rec.709/sRGB generally reach up to around 300-400 nits at peak on a quality display while HDR has a defined peak of 10,000 nits by spec. No current display can reach this yet, most are around 2-5000 nits (OLEDs are in the 700-1800 range. See AVSForum for discussions about OLED vs LCD/Quantum dot/Projector HDR nit levels).
This prevents users from using HDR levels of luminance for extended periods of time. More nits needs more voltage, more volts means not only faster battery drainage, but also more heat is generated and shortens the life of each OLED subpixel as the organic compound ages (more voltage quickens aging).
Image BURN IN is caused when some OLED subpixels have aged faster than others near it. This IS permanent.
Image RETENTION is NOT permanent yet looks just like image burn in. This is from voltage that has built up and can no longer be contained in the components controlling each pixel. Simply discharge them by turning the screen OFF (As in power off. I think Always On Display keeps them primed and ready for use). You could also look at animated full screen color noise/static patterns. This would improve uniformity by fully charging the components for remaining pixels. (ex: The old and free ".js" file version of jscreenfix. Present version is web based and not full screen).
If you're worried about being blinded by the high HDR nits, don't be.
The intent of HDR is to NOT cap peak brightness and provide a fixed gamma transfer function (layman: How bright something is relative to your display's darkest possible black and brightest possible white).
To explain what I mean, let's say we have two identical displays with an impossible 100% for color accuracy. And let us assume we have a perfectly mixed movie for both SDR and HDR (alot of movies are only graded once from the source material and then that graded copy gets regraded for the other releases. Basically this is bad but most movie studios are either trying to save money or simply don't care unless it's a "blockbuster" movie....
So again, let's say he have a perfect SDR and HDR release.
Side by side they will be 90% identical. The "HDR" levels are ONLY for specular highlights, like light reflections water/chrome/etc, clouds, sparks and other generally small details. Having something at 10,000 kits that is only, let's say, ~30x30 pixels isn't going to appear blindingly bright but will appear brighter in relation to the pixels around it (which again is the whole point of HDR).
Now for the other three screen modes...
Despite what you think you're seeing, CINEMA/PHOTO/BASIC MODES ARE NOT "TOO RED". ADAPTIVE DOES HAS TOO MUCH BLUE.
Adaptive is default, and by the time you get to the display options your brain has already adapted to this colder color temperature and you perceive the change as having too much red.
Instead of trying to explain why this happens, look at THIS ILLUSION.
The biological and science mechanics at the core of this illusion is exactly why you should NEVER compare colors by sight alone, and this is basically what happens when switching back and forth between modes after adapting to one mode. The rods/cones on our retina are not digital and takes time for them to adapt to changes in stimulation to light entering your eyes.
It appears this way because most displays come from the factory with a cooler color temperature than the industry standard D65 white point. This makes displays look better on a showroom floor under all their fluorescent lights. Simply put, if you think it's "too red", it's because you're used to seeing something that's "too blue".
Actually use these other modes for a day or there about so you have put real hours into looking at the screen, not just a few minutes of the day. Then try switching back to your adaptive settings. You may be surprised to find your opinion to be different about the other modes being too red.
This doesn't mean you can't prefer adaptive mode's saturation boost and/or cooler warmer temperature (aka a more "blue" screen), nor am I criticizing anyone who does not use Basic.
I'm just presenting fact, and not my opinion, based on data in regards to accuracy.
Personally I use Cinema mode and only switch to Basic for drawing.
TL;DR:
Adaptive has terrible accuracy, doesn't have a D65 white/color temperature, uses an HDR colorspace for non-HDR content (this is bad), and two levels of built-in saturation boost (RGB slider controls effect only one of these boosts).
Straight from the factory basic has color accuracy rivaling even the best ISF calibrated displays with a 3D LUT, has D65 white/color temperature, and uses same SDR colorspace that non-HDR content was made with.
I've done my own measurements with my own calibration equipment, and my results support their findings. Not that I doubt their results, I mean DisplayMate is known in the Home Theatre scene for their technical articles. If you don't agree with them then do your own measurements to get factual data for comparison. Human eyes are lying sacks of crap (read: adaptive) and you can search AVSForum if you need explanations and/or proof of this.
Here is DisplayMate's shootout for anyone enterested.
http://www.displaymate.com/Galaxy_Note8_ShootOut_100.htm

Just turned my phone to basic. Looks a lot better now. No more super bright cartoons colours. It also makes the colours of my graphic design logos more accurate.

I've always used Basic mode in all my previous Samsung devices inc my tablet.
However, the basic mode on the N8 shows a pink hue which is not tolerable to my eyes. Now, if the basic mode showed a true warmer tone like a slight yellow hue it wouldn't be so bad.
Talking of which, I was always under the impression that the term "warm" in respect of display technology meant whites would appear somewhat yellower , not pink like this display. ?

Isn't there an app to fully calibrate the screen?

If you're trying to compare how the screen looks by your eyes alone, you're doing it wrong. Look at Illusion link in my long post.
How that illusion works is the best "short" version of explaining why you think Cinema/Photo/Basic looks pink.
If you really want to know if the screen is in fact too red, or too blue or even green, you need to use calibration equipment (colorimeter, spectrometer/spectroradiograph, and software; HCFR and DisplayCal are free, Light Illusion, CalMan, ChromaPure are expensive.
Getting your own gear is quite costly, but you might be able to rent it for half a day or so for a fraction of the price. If anyone is even remotely interested in this go to AVSforums.
I've actually measured 5 others (1 European and the rest USA variants) besides mine (Korean version), and every one was within the repeatability tollerances for my i1d3 pro. I don't think there will be any differences from manufacturing randomness due to how accurate they are straight from the factories, and I feel the same for any regional differences.
I'm not trying to offend anyone, but you are extremely likely to be wrong if you think Cinema/Photo/Basic modes are too red/warm using your eyes or another display as reference. Human eyes will adapt to warmer or cooler color temperatures regardless of accuracy, and factual data from tools all point to those display modes having amazing accuracy (See DisplayMate's shootout).
As for the question about color temperature...
The visible spectrum of light the typical human eye see will see more green colors than red and blue combined.
Blue is the portion we see the least of.
D65 is the standard white point which is based on the spectral pattern of light from the sun.
Since white is all colors, having D65 white means colors will interact with other colors realistically so there is no drastic change in perception around other light sources like tinting only under fluorescent lights but not incandescent lights.
Warm and Cool are how we describe which corner on a CIE chart a white is closer too in relation to where D65 is.
The above isn't totally true, but I didn't want to go into detail, but it's close enough I think. See AVSforum for the truth from people far more knowledgeable than I, like real ISF certified calibrators, Calibration hardware/software companies used by movie studios and scientists, etc).
Try using the phone for a couple of hours straight while set to Basic, then go back and change it. Do you still think it looks pink?
Before I forget again, it's possible a screen protector can cause a tint, as the material of the protector and any coatings it has (polarization, anti-glare, oleophobic, etc) will change the spectral distribution of the primary colors red/green/blue. This will change your perception of color based on your environmental lighting. So it could look perfectly fine in one room of your house and different in another if they had different types of light. That's just an example, as there are so many types of lights and each have their own color temperature and spectral distribution. Not just like incandescent vs fluorescent lights, but various types of incandescents (size, shape, power consumption, bulb material, diffuse coating, etc).

Android does not have any real color management, so you can't really calibrate the screen.
It's not really needed with this models' display, from the factory they are one of if not the most accurate displays you can get. It is on par with OLED displays with a 3D LUT that are used by movie studios for color grading.
Take a gander at DisplayMate's shootout for the Note 8. This is a technical analysis made by DisplayMate who's business is dealing with grading level accurate displays for those studios.
I just realised I may look like I'm advertising for AVSforum. I'm not.
It's just that what XDA is to Android and related stuffs, AVSforum is to home theatre and related stuffs. Actually they're better as they actually have active "official" members of the industry and not representatives. It's great being able to talk to people at or close to the source. I say active because they're not just there to advertise or sell you something. You can learn 99% of everything about calibration, for free, from the same people who's job is calibration or ISF instructors who hold paid or college classes. The equivalent type of people missing from XDA would be like engineers, lead techs and top level technical people from smartphone divisions from all the companies.

I think for colour accuracy it also comes to personal preference, like for sound equalization.

I used mine initially in the AMOLED Photo mode but did notice that colors were oversaturated. I've since switched to Basic mode and so far prefer it to the other modes. No, it isn't perfect, but whites are more white than Adaptive mode and colors are less over-saturated than the other modes. AMOLED Photo would still be my second choice. Adaptive mode has whites that are much too blue.

I found amoled screen to be really dependent to orientation. In the best one it is better than IPS and in all the other ones it is worse. They really got to fix this.

Accuracy is NOT and NEVER WILL BE personal preference (unless you prefer accuracy, lol). Preference is an opinion, and has nothing to do with the truth. I prefer Cinema mode, despite knowing Basic is the most accurate mode for all content shown on the screen (HDR will trigger HDR mode, which use completely different settings.)
In this case the screen accuracy is referencing the standard it was made for (BT.2020 and Rec.709).
You're free to think Basic looks too red, but there is a 99% chance that you are wrong (<1% chance due to bad screen protector materials/polariaztion filter/dot matrix/oleophobic & other coatings and your environmental lighting).
Again, the screen is one of the most accurate displays ever made. Take it to any calibrator (not "geek squad"...) and they will get the same results as DisplayMate... assuming the calibrator has a spectro to profile his meters to the amoled screen.
I won't even get into sound. I'll just point everyone to Head-fi.org forums as well as AVSforums. Way to many variables to cover, even for IEMs which take your "room sound" out of the equation. Both places will do a far better job at explaining the science behind everything for audio and (digital) visual things. And yes, real science. Everything I've mentioned has hard proof (measurements) and not ancedotal or biased opinion.
None of this means you can't like something that's "not accurate". Just wanting to make it known that yes many don't know what they're talking about (Not trying to be rude here. Just sayin').

Bs, who tells you I have the exact same eye as you. Who tells you present measurements or even science covers whole phenomena variables (plus Godel and other scientist prove science can't completely theorise a phenomena).
Unless you have attended to MIT or Princeton chances are you haven't achieved science study level I have.
I don't appreciate the haughty way you commented my post.

What's your screen issues. ? Just out interest.

No real issue but I am not satisfied with the way greens are displayed, like on vegetation pictures.

This is probably true, however, I grew accustomed to a more blueish white, that the basic mode appears too warm now.
I remember last year, after trading my Note 7 for the second time and going to the LG V20, that I thought the LG had a way too bright white, noticeably more blue. However, after having had that for about a year and finally switching back with the Note 8 a few days ago, the basic just doesn't feel right anymore. I really like the adaptive (that is, with a few minor adjustments to the sliders), but whenever I am in a game or watching something, then the adaptive mode has way too much saturation. Then the only thing that does help is switching back to Basic mode, but I get annoyed by how warm it appears to be as soon as I hit anything with a white background (like settings or text messaging). The laptop I'm writing this on also has a more blueish white, my Samsung SHUD TV seems to be somewhat in the middle of it all but less red than my Note.
While basic may be the best setting, I can't say I really like it. Switching back and forth between the modes is a workaround, not really a solution. I really want to like this phone, but it is quite an annoyance to me personally, even more so when I consider I'm paying 950 USD for it. I am going to give it a few more days to see if I can get better used to basic mode or if I am going to return it to the store. It saddens me a bit that there's no option to add a little bit more blue to the basic mode, which, to me, is really all it needs.

I would also like to add more blue even to adaptive mode.

Although a different device, the basic mode on my Samsung tab S2 LTE is awesome. It's a night and day difference to the Note 8 , albeit both adaptive modes on both devices are closer in my eyes . However, the basic mode on the tab s2 doesn't go pink but a more warmer yellow type mode.
I agree with you , the basic mode in my eyes on the N8 is rubbish.
