Hi,
I also had this problems with deep blue saturated colors in darktable
with my cameras (D3100, Om-D EM10)
I think its caused by the combination of basecurve and input color profile.
You can try "linear Rec709-RGB" in Input Color Profile.
Best solution for me was to calibrate my camera with darktable-chart and
IT8 Target by Wolf Faust.
This creates a style with LUT-Module and tonecurve.
Now the colors are very close to in Camera Processing.

Coincidentally to the post by Per Östlund, I also have an issue with
blue colors in an image.
In an image of blue-violett pansies I get strong fringes, especially
around out-of-focus blossoms. See the dark flowers (OOF) on the right.

Gamut clipping does not really help. The problem does not happen with a
disabled base curve.
Is there a better way to deal with this than to disable the basecurve
and get the contrast back with the tone curve?
Could someone more knowledgeable shed some light on what is happening
here? It doesn't look like a blown-out blue channel to me.
TIA,
Oliver
