Sorry, I wasn't clear.  The issue is that the colors are inversed in mono
although they shouldn't.

I guess Atari TOS looking bad is TOS problem as things look better
with EmuTOS.

And this happens also in Hatari v1.0.1 so it's not a regression.
The colors being wrong are.

Your latest version in the repo seems to have fixed things for 2 & 4 planes,
but the 1-plane (mono) mode shows still inversed.
