That doesn't make any sense.I’ll give you an apology when you tell me which oled iPad Pro you personally own and returned for a bad screen, until then I stand by what I said then and now. Cheers.
FACT: there is an OLED grain-issue on a fraction of panels. Grain is erroneously pronounced in some panels.
When I tried explaining it was a manufacturing defect, you then dismissed me, told me it was "highly subjective and only evident under a very contrived situation." You kept saying this because of solipsism—you couldn't imagine other iPad Pro users had different quality panels, and were having a worse experience other than your own.
Correcting you was an exercise in frustration. Today you change your tune and I'm so proud of you.
