Static image, burn in?

I accidentally left a static image of a game I was playing for an hour or so after suddenly falling asleep in the middle of my sesh. (I know, it’s stupid)

But do you think the condition of my phone screen’s all good?

‘Cos I have read and heard that the OLED screens are susceptible to image retention or burn in.

My phone did not lock itself on this particular incident and after checking the battery usage, the static image on the game was left on for an hour with around 30% brightness.

Excuse this nonsense, I just want to find solace for my worry. Thanks! 😅
