Hi Tobias,
I recompiled darktable with the modifications. The result is slightly
different but the blue shades are still affected on a reduced range.
I also tried with Digikam and rawtherapee. The jpg images with sRGB
profile do not show alterations. I tried the RT_sRGB profile within
darktable and the image was correct.

Hi,
Exporting images with the default sRGB(web) color profile, give
sometimes bad results particularly in blue shades. Using an external
sRGB(Sony) profile solved the problem. The issue is present in darktable
2.0.3 and 2.1.0+961~g978f96c with lcms2 version : 2.6-3 .
Are you compiling darktable yourself? If that's the case, please try changing
the file src/common/colorpsaces.c as follows:
line 1269: replace "++in_pos" with "-1"
line 1274: replace "-1" with "++in_pos"
then recompile and see if the result is better.
Attached image : upper image result with the internal sRGB, lower image
result with an external profile (Sony Corp sRGB). The problem occurs
with all the image formats (jpg, tiff, png, etc.)
The original raw image from a Sony ILCE-6000 is available here :
