I have a Studio Display that is perfectly fine. I don't need perfect blacks. I just expect a panel that doesn't have a pronounced blue image in the corner and whites that are uneven.If you're so sensitive about this (to be honest, I don't actually see what you're claiming in your photo), then you need to get a monitor with MiniLED backlighting or an OLED.
Its sort of hard to photograph because phones naturally try to even out something light and don't capture the nuance. My wife walked into the room and asked 'why is it so blue in the corners?' with no prompting haha
