I remember this thread with the G3, http://forum.xda-developers.com/lg-g3/themes-apps/super-amoled-contrast-g3-display-t2817248, and noticed the setting exists for the G4 as well. It's under Accessibility > Vision > Screen Color Adjustment.
Has anyone played with it to improve color and contrast of the G4 screen?
I gave it more contrast by dragging the circle from the middle of the top down over the first blue candy. Tried to keep the same colors, but more contrasty. It's hard to adjust accurately.

As per the link above, already discussed.
Not worth it, ruins the display clarity and accuracy. it's not a true enhancement.

just picked up the tab about an hour ago, and just started playing with it... so far, so good
the one thing that stuck out at me so far is the color... it's at least 300-500K too warm, and waaaaaay to vibrant...
is there anyway to tone it down a bit ?
I couldn't find a way to adjust/calibrate the color on the device. I wanted my photos to look correct ... so I created an action in Adobe Photoshop that correctly adjusts the photos before I download them to the SGT 10.1.
Below is a copy of a post I made on the post processing forum on fredmiranda.com:
A little work allowed me to create a Photoshop action that will take images from my normal calibrated NEC 2690 work environment and apply a transform that preps them for use on the Galaxy Tab 10.1. In case anyone needs to get images looking good on a tablet, here is what worked for me.
In Photoshop, I created three adjustment layers.
1. Hue/Saturation - Reduced saturation (this was to overcome the highly saturated LCD on the Samsung).
2. Curves - I adjusted the individual RGB channels in the curves adjustment layer to get the right color balance on the tablet.
3. Exposure/Gamma - I reduced the exposure slightly and adjusted the gamma value to offset the gamma on the tablet.
Then resized the image for the small screen and applied appropriate sharpening.
I standardized on using sRGB for output. I left the original images intact ... this action can be used to create a a custom set of images for display on the tablet.
The good news ... I ended up with a beautiful tool for sharing images.

i guess that's the workaround...
not sure i like having to work around the color issue, but i guess it's better then sitting in front of a booker explaining why the model looks like she just took a bath in orange juice
I think turning off Auto adjust screen power in the screen settings helps the reds a little. There is also an app in the market that will let you adjust the RGB but for the life of me I can't remember what it is called. I uninstalled it because it made the launcher laggy but other than that it worked OK.
Found it: color filter service is the app. Its 99 cents.

will definitely try this app...
rgb controls would be ideal, and will allow me to use a colorimeter...
thanks
My Brother-in-Law asked me the following.. Can someone assist in answering this question..
On iOS, I use two accessibility features extensively: Zoom and color inversion
By making some Accessibility selection, I enable these two fingers.
With a three-finger double-tap, I can zoom the screen. The entire screen image is zoomed. I can then adjust the magnification level at any time Also, I can scroll around the screen to see the parts that are now offscreen since we’re zoomed. I use this al the time since I can’t easily see small print on the tablet.
Next, if I triple-click the Home button, it inverts all the colors on the screen – this helps me because sometimes I can’t make out dark text on a light background very well. The inversion makes light text on dark background which is often easier to read.
OK, nice apple features.
ICS has font size adjustment, color inversion, and contrast.
Touch control, talking robot feedback, voice control, to name some.

Hi! I have a 9506 variant, with a screen with slight color difference across the screen from top (cooler gray) to bottom (warmer gray).
I know, there are many such cases on samsung's amoled screens, and I also found that Cyanogen has a screen calibration, which can change the temperature for the whole screen. But is there a solution to fix not the whole screen, but partially, according to each screen's characteristics (user adjustable)?
You're probably looking for a screen filter app with adjustable overlay.
Though I don't think there are many apps with such a feature, as there aren't many requests for partial screen overlays.
Try CF.lumen. It was designed to adjust color temperature on the fly.
After changing to starting wallpaper, I noticed darker lines between the shades of blue. Is that how it's supposed to be? I don't remember it being like that when I first got it.
I tried googling pictures and videos where I could find color fades. Those lines where mostly there, but not as noticeable as on the wallpaper.
I don't think it's a display issue because the problem can easily be seen on the screenshot. i(dot)imgur(dot)com/F5S4mLE.png
Phone is set to High performance, Adaptive display, colour balance on the middle.
I also have another question. Is music player supposed to show these vertical lines when there's no art for the song currently playing, i(dot)imgur(dot)com/JfKc2Ll.png ?
All of the applications are up to date, so is the software. Didn't try factory reset tho.
That's how your phone renders images. If it was a screen issue, it wouldn't be visible in a screenshot.
Try some of those wallpapers especially created for S8 and see if the problem persist. IMO, I wouldn't consider this an issue.
Hello, is there any way to change the screen temperature of my device after rooting it? The blue filter of this tablet is very bad, as it does not change the relative values of the colors, but overlays a layer of color over the entire screen, thus spoiling the contrast and making the black colors horrible.
If you can provide any information about this, I would really appreciate it.
