I still don't know enough to say I know what the difference is caused by, but 1000, compared to 6400 iso has to be almost 2.5-3 stops, so the Zf should come out much lighter.

Ok,
I rechecked the shooting menu.

I discovered a missing setting in Picture Control:
Zf was "Standard", instead of "Neutral" in Z30

Do "Standard" saturate colors more than "Neutral?

In my experience, yes.
