iPad Pro How can I check for potential issues in my new M4 iPad Pro?

[Ramoncitos]

Hello everyone, the iPad Pro M4 13" arrives on Monday and since I know I have 14 days to test it and return it if I find any problem, I would like to know:
1) how to check if the screen has the problem that has been found on many of these ipads with the grainy screen
2) how to check if the screen has light leaks
3) how to check if the screen has hot pixels (always on, white), dead pixel (always off, meaning it looks black) or stuck pixels (one or more subpixels (red, blue or green) is always on or always off)

I would appreciate all your explanations because it is my first ipad.

Best regards

Ramón

I did not know this was an issue. I bought mine, started it, looked at the screen in different scenarios, saw no issues and lived on, with a new iPad Pro...

OLED is not backlit so there shouldn't be "light leaks". Black will be black.
The grainy issue, I did not have on mine or I just don't preceive it but you can read up the various threads on it. Most prominent on gray background at medium/low brightness settings.
You can check for color shift, trying viewing off axis. I've seen a few M4 Pro and it varies, mine has a red shift off axis, but I've gotten over it.
I've used this Eizo monitor manufacturer page in the pass to check my ASD, it's fairly simple for checking dead pixel:

Also make sure you turn off Apple's True Tone and Night Shift when you're checking your screen.

Same here. On my sixth iPad.

Hasn’t been any issues with mine. In fact, compared next to a Surface and new MacBook Pro, the iPad is better than both of those.

Just to add, and this will sound silly, but use it for a good 30-60mins non-stop to check if you suffer from eye strain/headaches due to the PWM flicker of the OLED panel. I never had this issue on OLEDs (TVs, phones, monitors) until I bought the M4 iPP. Had to instantly return it.

Any of these issues should be rather straightforward to see when using the device. Not that I have ever encountered any of them.
