Debatable, it's not what those content creators say, and I definitely wouldn't call it alarming if it requires you to stare at gray background in a dark room. It isn't even half as bad as IPS backlight bleeding or VA angles. Different people have different standards. You don't have to buy it if you don't like it.
> Adding one more reference, here is a recent post to /r/monitors showing burn-in after 2 years of constant use
Pixel clean cannot run if the monitor is constantly receiving signal.
Also show me an IPS after 2 years of constant use. The backlight can degrade as well.
[edit] Furthermore, 3 year warranty covers your burn in, so I guess they would happily replace your monitor once the burn in normally visible. [/edit]

> I've experienced burn-in on my pixel 3a after 2 years
2019. My Nothing Phone 2 is from 2023. I've been having it for 1y 8mo+ and experienced zero burn in on the same gray test. For reference, I don't use automatic brightness and it's almost full-brightness all-day (except evenings).
