Check settings - display - Blue light filter. If the switch is off BUT it says Custom Schedule underneath, it's NOT OFF. Click on the words Custom schedule. On the next page there are two switches. Turn on now and turn on as scheduled. Turn both of them OFF. 

Let me know if that got it.

Hello @userX23s2XsHde ,

@Big-Bad-Brad is absolutely correct, check to make sure blue light filter is not turned on. Also based on the picture you attached I can see some noticeable lines in the screen. Your problem could also be stemming from the need of a screen replacement.  Whenever a screen needs to be replaced it will sometimes show some discoloration much like what you described. If @Big-Bad-Brad directions do not resolve the issue I suggest going into one of your local Samsung or U Break I Fix locations for inspection of your device.

Even I am having the same problem..Screen color is little blue and yellow mix. Moreover, Screen is blurr with lines across. Called samsung help centre..As expected they asked me to do factory reset. Even though I know, It wont work with factory reset. Still I did and no use. 

Funny thing is: They are asking you to goto service centre thinking this is screen replacement issue. How many samsung note9 users will get this issue all of sudden. 

If samsung having intention to look and understand. They can reach out to me and i will show behavior of my mobile.

Note: When i keep display brightness to low or very high. There wont be any issue. If i will bright ness to medium, then only this issue coming. So, this is not screen replacement issue.

Worst part is Samsung went ahead and released this update to some more devices in May 2020.

Yeah, unluckily, my dear note 9 has same problem but more serious. The screen is like a blue mix yellow and no any touch responsed. I think about screen replacement for not keep using it but to take back my data. What a poor flagship!

I've got the same issue after software upgrade!!!! It's frustrating for the phone to keep discolouration. If any Samsung tech team is in this chat group, please review the issue!!!
