This weird screen behavior was observed when I first used a parallax wallpaper application (FYI - it's the 3D Parallax Background by Vinwap).
When I set my moving wallpaper to an image that depicts a starry sky (i.e. lots of white little dots that subtly move when tilting the device), I noticed that the screen would show some visible horizontal flickering at the same area the sky sits.
The effect gets more noticeable as the brightness gets increased. For your reference, I attached a screenshot of my wallpaper to demonstrate what kind of image is required to replicate the issue.
Any ideas on why this issue might occur? Is it a common thing across AMOLED screens, or just another problem with OnePlus 5 panel configuration?

Hi,
Few days ago I purchased a new unlocked n910f from a nearby retail store and I noticed something strange with the display.
The issue is - vertical lines are visible if a gray image is displayed. This is visible at brightness levels above 50%.
Same can be seen if a white image is displayed (i.e. a white page in Chrome or in Settings) and the notification tray is pulled down so the visible content of the previous screen becomes dim. This problem is really annoying...
I've created an image with photoshop, 2560x1440 with a #2f2f2f Gray and opened it with Gallery.
The display settings are: Screen mode - Basic, Auto adjust screen tone - OFF, Brightness at 100%.
A screenshot doesn't show any vertical lines...

I've searched for this issue on the web and XDA, found about Mura effect, but nobody pointed out this issue on Note 4 and if this can be fixed. Is this issue present on Your device? Should I request a device replacement?
Thanks,

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.
Does anyone notice banding on their display, mainly when viewing grey or black backgrounds? If so is it a hardware or software issue?
I used a solid grey background image in landscape view so to fill the entire screen to see how bad it is. I wouldn't say it's bad but definitely noticeable.

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.
