iPhone 13 Pro shows two tones on screen

Hello everyone.

I recently purchased a brand new iPhone 13 Pro.

On second day of use y raised the device and noticed that the upper part of the screen shows the regular color (near battery icon, and telco company), like a rectangle with the real color but the rest of the screen shows a darker tone and instead of white screen in menus you can see like beige color.

It looks like the interface has a transparent rectangle in front of me.

I tried reset, hard reset, and restore all factory and it initiates fine but after the first off/on screen the dark rectangle appears.

Any idea?
