Dark mode is not black. Why?

[Toninello]

Can you explain why dark mode is grey and not black?

How do you change this?

I use nova launcher. Listen ...

This is really weird! All is in dark mode!

Take Facebook, Messenger and Google Photo

Take my S21U and my Xiaomi

How they look

                  Facebook   Messenger    Photo 

S21U.            1 Grey        3 Black.       5 Grey

Xiaomi.        2 Black.     4 Black.     6 Black

Then, make a screenshot of all these samples and you see

1 and 2 both grey on S21U and both black on Xiaomi

3 and 4 black on both S21U and Xiaomi

5 and 6, like 1 and 2, both grey in S21U and both black on Xiaomi

W da F ???
