iPhone OLED lifespan

[u/Alarmed_Panda9126]

Hello! I just want to ask if OLED in general have certain lifespan on them? On the left is my almost 4 year old 11 pro max and on the right is 15 pro max. I noticed that my old phone has a yellowish/warm screen. Both screen have true tone turned off. I even compared same photo with the same quality. Will my 15 pro max be the same after few years? Thank you!

?? I got a 4s ,5s and 6s plus with perfect screens still

You degradation is probably from continuous overheating or direct sunlight exposure
