If you want a different anecdote, I have a LG C1 that got burn in after a year of use, playing FFXIV. I can see a blue outline of where my minimap and hotbars are. HUD burn-in. The only thing I disabled was the dimming feature, because it's outright annoying to use, where every time i'd scroll it'd make the text on a page illegiblly dark. (Dark mode pages, white text becomes dark gray while scrolling then back to white when stopped... sometimes not!). I moved that TV to the living room and got a non oled samsung instead which is what I use now.
