That looks like a type of Thin film interference, like you’d see on an oil slick or a soap bubble. Wikipedia says:
I’d guess the display uses a thin film on one of its layers causing this rainbow interference pattern that shifts depending on viewing angle.
So if that’s actually just a guess, I’m impressed, and you must have some experience in thin-film lol.
LCD panels actually use a thin film of silicon (I think it’s silicon) over each pixel. And cheap panels using TN technology often have this issue and very poor viewing angles.
Or roast beef!
