Everyone uses their OLED different to others, it's a lottery panel some get burn-in others don't on different models it is as been a big debate for a long time, and I am not scaremongering anyone it was some tips that was written on AVS forum that I copied to this forum, I also an OLED owner
As I said above its how you use it mate, to avoid the possibility of burn-in is to mix you content don't play the same game every day for weeks drop the OLED light to 40 look it up and Sony and LG said the best way to prevent burn-in or image retention on their TVs is to avoid static images

It isn't rubbish
Used to work at a place running print servers/rips 24/7 and more often than not someone would forget to turn the monitor off and leave it sitting on the EFI dashboard all weekend, sometimes two weeks over Christmas. An old iMac developed burn in from one of the hard interface lines, not all screens were susceptible to burn in but it put into perspective how long it takes for an image to permanently burn into a display.
with dimming, screensavers and auto power off switched on you have little to worry about. The online guides and advice are for people who don’t know any better.
