Test your device also(see below)
and please comment if your device(with model and android build) is also effected

Devices Tested(confirmed):
-Galaxy Note 10(latest android 9)
-Galaxy S10(latest android 10, and 9 also)

Bug
-The tested phones cannot display different shades of low brightness colours(dark gradients) properly.
This results in Banding/posterisation of colours.

-It cannot be seen in screenshots properly so I have attached photos of my phone when playing videos.

Test:
-Set your( very Important⚠️)
     •Auto brightness-off
     •Brightness-Maximum
     •Video Enhancer-On
     •view the video in a dark room
      (Apply these so as to best appreciate the dark colours effected, the bug is present even without these settings)

-Play the following videos in your phone
        (Look for banding best at 00:10s)

-Play these videos with full brightness in other phones also if you think this is normal, preferably a non-samsung device(like OnePlus or iPhone)

-Please comment if you also have the problem with your device details as we need to send our message to samsung executives.

Believe me and take my word for it, you can unsee it once you see it and I have owned my Note 10+ for 2 months but only came to notice this horrible banding only last week.

I am 100% sure it was present in your device since the 2019 match update (after my research)

I have confirmed that this use is present in all models after Note 8(S9, N9, S10, N10) and that the galaxy S8(I own one) was the last phone free of this issue.

Worse is that this issue is present only in some particular batches of samsung phones

Post a photo of your device which is taken by another phone in a dark room displaying this issue.
