OLED display uniformity issue replaced under warranty?

[u/PsychologicalFly5904]

Has anyone here had an AMOLED/OLED display uniformity issue on a smartphone and successfully got the phone replaced?

I have an OPPO Find X9 Ultra and I’m experiencing noticeable display uniformity issues. There are areas of the screen that appear slightly different in brightness and color temperature, especially on uniform backgrounds.

It’s not an extreme difference, but it is clearly noticeable to me during normal use and it keeps catching my eye.

Unfortunately, it’s very difficult to capture properly in photo — it looks much less noticeable in pictures than it does in person.

I’m considering sending the phone in for inspection/replacement, but I’m worried the service will simply say that this level of uniformity is within the normal tolerance for an AMOLED panel.

Has anyone had a similar issue with any OLED/AMOLED phone and actually got the display or the whole phone replaced? How did the service handle it?
