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.

It is not a solved problem. Play some games in HDR on a daily basis and their HUDs and character portraits will burn in. As simple as that. I have an AW3423DWF that did just that after 2.5 years of use.

I have an Alienware and it took a while to burn-in, I think I noticed for the first time after around a couple of years.

AFAIK, burn-in is inherent in the technology; there's only mitigations.

Seems like it really isn't though. The TechSpot findings show the inverse burn-in line down the middle, subpixel disparity, and brightness deterioration. I think you can argue the latter two aren't big deals for casual users but the line down the middle of the screen seems pretty galling.

At least for OLED TVs, rtings.com has been running burn-in tests and has noted that supposed technological improvements on OLED longevity haven't really done much: https://www.rtings.com/tv/learn/oled-burn-in-not-improved-as...
