iPhone 11 Pro screen problem - Stuck or Dead pixel, help!

[Angel_Wings]

Hello! Can anyone tell me what this might be (photo in attachment)? Two days ago I updated to the new ios 15 and after that I detected this miniature red dot uo on my screen. First I thought it’s some dust under protection glass, but then I renoved it and it’s still there, in my screen! My phone is 7 months old, I take a good care of it, I’m so scared. I read about dead and stuck pixels, mine is only seen on light background and a bit dark blue backgrounds, but when it’s black background it can’t be seen. Also, it isn’t viewable on screenshots. I think it might be stuck pixel and not dead, but I’m not sure. Please help!

If you can’t see it on a screen shot then the display has a problem.
Either replace the display or change the color of your background image.
