New Mi6, At The Top Of The A Display A Brighter Line, Normal?

[GAm7de]

Hello,

After the Mi3, Mi4c and Mi5 I bought now a Mi6.

The first thing what i have seen is a brighter horizontal line in the top of the display.
If the background is black, all is fine, with brither colors green, blue the line is better visibly.
Is that the same with your Mi6, or did I have only bad luck with my Mi6?

Thanks.
