Avoid cranking up the OLED brightness over 70% for static content and absolutely never drive SDR-Reds into the HDR range by using fake HDR-modes when having brightness high.

I have a LG 2018 OLED that has some burnt in Minecraft hearts because of that, not from Minecraft itself, but just a few hours of minecraft Youtube video in those settings from the built in youtube client, but virtually no other detectable issues after excessive years of use with static content.

You only see them with fairly uniform colors as a background where color banding would usually be my bigger complaint.

So burn-ins definitely happen, but they are far from being a deal breaker over the obvious benefits you get vs other types of displays.

And driving everything possible in dark mode (white text on dark bg) on those displays is even the logical thing to do. Then you dont need much max brightness anyway and even save some energy.
