M1 MBP with uneven keyboard backlight, Any solutions?

[Nisounas]

Hello,
I noticed that the lighting of the keyboard is uneven, you can see below a video I made the keys "Q,W,1,2,3,-,+" are more lit than the rest, while the other keys seem not to be lit.

This problem is not only on my Mac, I found at other owners with exactly the same problem the same keys:

MBP PRO M1(not mine)

MBP PRO i5(not mine)

I don't think there's much that can be done, it stems from the way the light is done with lightpipes for energy efficiency I believe, rather than individual key illumination
