Do all screens on these iMacs turn yellow?
I want to replace the screen, but it seems they all turn yellow at some point …
My screen reference is LM215WF3 (SD)(A1)
Update (07/12/2019)
I’ll try to fix it it, and if it fails, I’ll go for a SD B1. Big thanks from Belgium @oldturkey03 and @danj for those precious advices ! :)

For those still searching for an answer on this issue, I have spent hours replacing the foil reflector tape that was burned on my iMac only to see no improvement with the yellowing issue. The root problem lies with the LEDs themselves - the clear cap on each LED has yellowed over time and tints the light emitted by the LEDs. Replacement LED strips are available on AliExpress for a reasonable amount but be prepared for a lot of work to install them.
