I didn't watch what this guy did, but honestly I doubt it's going to be a problem in a normal use scenario. You don't remain on the menu very long, a lot of games move or hide their hub, etc. I mean, it takes a lot to burn an image in.I have a Steam Deck OLED, i hope it does not get burn-in. I did expect it could be at some point, but 700 hours seems pretty low... Hopefully if it happens Valve is fast with fixing it
