Weird scratch/crack lines on a brand new fenix 7 solar edition

Hi Garmin team!

I've recently bought a brand new fenix 7 solar watch. Have to say that it is a pretty awesome piece of hardware!
Although one thing really bothers me. When I turn on backlight (100%) at night, I can clearly see two strips/mini-cracks inside the screen. Watch is literally brand new, just unpacked.
There are no scratches or any damage on the surface of the screen. And these "cracks" are visible only when backlight is enabled, e.g. I can't see them under the direct sunlight.

 


Are these lines something expected with solar panel? Or this is a warranty case?
