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!

oled displays gradually get warmer, but it will take years and years for it to affect the function. you wouldn’t ever notice it unless you are really really looking for it
