Screen brightness poor

Hi
I recently had my Huawei P30 Pro fixed and the screen brightness is terrible. When outside, even if cloudy, you struggle to read the screen.

This was definitely not the case before I had the screen and battery replaced. (was 3 years old, and the screen had some moisture in it from a very rainy hike). The phone shop (not Huawei, as outside of warranty) said they used official Huawei parts.

I barely notice a difference between brightness halfway and brightness to full when I adjust it manually. It doesn't even detect that it needs to put the brightness on full automatically when I'm outside, which is strange.

Any ideas?
