I've noticed the display on my note 20 ultra is significantly dimmer than my Samsung note 9 and the whites look grayish. What should I do? This is very disappointing.
I've read that disabling the apply dark mode to wallpaper in dark mode settings helps with the washed out look.

When you reset the device or turn on the device for the first time out of the box, the display doesn't reach proper full brightness when you put it on max brightness. I know this because I have the Exynos version and recently when I got my Snapdragon, it was dimmer even with both on full brightness.
I think this is because when you first use it, the AI algorithm for controlling brightness still hasn't learnt the proper brightness levels (only my theory).
What I did to fix it, was I turned on adaptive brightness and set the brightness bar to maximum, then I put the phone under a bright spotlight for a few seconds then took it away. Then repeated this like 3 times. After that, when I set both phones to maximum brightness they were exactly the same.
I think when you put it under a bright light (or sunlight) it fixes the issues by calibrating the brightness higher.
Let me know if it works for you.
