Ok, I think I got it.

Gimp shopws some tooltips and explains that the treshold is the value below
which everything is considered noise. I think it might be useful to add this to
digikam as well.

Further. If I set Y and Cb to 0 I get the full blue noise. Increasing the
treshold for Cr does not change anything about that so it seems that digikam
has a bug.

Increasing Cb gets rid of the blue noise.
