iPad iPad 9 turns red at an angle

[Principalideal]

Hello. I recently had my iPad 9 tinted left edge replaced with a new one under warranty. On the new iPad 9, my screen now turns red at an angle. This interferes with the use of True Tone features and simply distorts the colors. Can you tell if you are experiencing the same thing? The Apple service center has already refused to replace this iPad 9 for me, but I simply cannot use it with such a screen.
