It seems burn in only happens in extreme cases.
Depends on what u consider extreme.
Watching 600 hours of tv a year is extreme for me, for somebody else it could be done in a month or two already. My oled tv basically only gets used for what 100 hours a year at best. However my monitor for my PC is on 21 hours a day, with probably 12 of that actually displaying something then a black screen. These oled screens will burn in hard as even that guy in that video has burn in after 800 hours and pc is riddled with static screens which is what linus shows on his video is something i 100% expect to happen.
Oled is great, if you don't use it much, or use it limited, or got money enough to drop a new screen in once in a while.
But the main issue currently for PC oled has
1) burn in
2) price ( 1k+ starting is way to high )
3) size ( way to big for desks )
4) to high resolution ( 4k not much people care for )
5) low hz ( higher hz is probably faster burn in )
Oled needs some serious tooling to be considered useful in the PC space that is.
