I feel like OLED burn-in is a solved problem. I picked up the greatest and latest from ASUS 1 year ago and compared to my oled from 5 years ago, there's zero visible burn-in and there's zero compensation cycles (that I can see, which is a huge upgrade compared to previous generations). Actually my old "monitor" is now a TV and all the burn-in from desktop use has disappeared.

edit: I put up a very aggressive version of grey which used to expose full on black spots on the older OLED and I can only see a very faint line where there is a full white bar from one of the applications I use, actually I think that's just my vision since I can't see it anymore.
