I just turned all the lights off (even the Christmas tree) and ran through a handful of usage situations and couldn't see any issues. I turned some lights on and did the same, I couldn't see any issues. I asked Claude, and got told to do the finger test, and that is barely perceptible. I then used my phone to record the screen and yes - I can confirm that there is an effect that my pixel 9a's camera picks up, barely noticeable at 240Hz, and definitely noticeable at 480Hz.

Basically I just trust IPS more than any other technology :)
In terms of text clarity, "2k" OLEDs (1920x1200) are a bit blurry. IPSs and 3k OLEDs are noticeably sharper, with not much difference between each other.
allow dimming display beyond normal max dimming:
xrandr --output eDP --brightness 0.5
restore to normal brightness range: xrandr --output eDP --brightness 1
(substitute the actual output name for your display instead of eDP; run xrandr without args to list)Hint: the only one was released in a year that ends with 25
