I have checked the panel background color are a bit different and darker from what windows does have.
I have take many screenshots to compare, and I summarize with this results here:
Right now the panel background uses: rgba (0, 0, 0, 0.9) as you can see it is very different from "windows 10", The closest that I could get to the windows version is: rgba(10, 10, 10, 0.8) as you can see on the imagem above is a lot closer to the windows 10 behavior.

To change it, just change from
rgba(0, 0, 0, 0.9);
torgba(10, 10, 10, 0.8);
