Damn, and I thought that my display was faulty 😅 I experience the same thing on Taranis QX7

I believe this is related to the number of items shown on the screen... if you add a telemetry sensor to the telemetry screen, or add a SF/GF, the contrast should lighten to match the rest of the menus.

Contrast is set once and for all at start, and does not depend on screen content. This is due to the screen itself whre it's power driver regulation is not what you would like it to be

[pfeerick]

That is not correct - at least not as far as the appearance of contrast changing dependent how much on-screen content there is. If you add one or two functions to say GF or SF screen, it will lighten to be the same as all the other screens. i.e. As if the screen updates faster when there is less content on it, and slower when there is more, rather than being locked to a consistent speed regardless of how much content there is onscreen.

is any way how to fix it?

No, the best you can do is find the value that makes most screen ok, but it is not possible to get all of them perfect
