If I understood correctly, (a), darktable will use raw whenever available; (b), raw does not use any particular color space, such that the meaning of the color values is open to interpretation. (c) darktable compares the raw files and the jpeg (at least in some calibration run) to determine a base curve aimed at fitting the raw data to the jpeg. (d) darktable internally uses an independent color space like XYZ or Lab. If all this is correct, then import of the raw data should reach almost immediately the internal representation, such that each color has a very well defined meaning. Where does the input color space fit in here? Does that make any sense with raw? Or should it only be used for jpegs, which use a particular and known color space, such that the trick fitting raw data to some jpegs is unnecessary? > I haven't found yet any use for output profile. > It sets how the colors are displayed Yes. This is, what I would expect for one. But exporting a collection for printing or web may be onother reason to choose a different output color space or profile (if it where for a particular printer).

Wouldn't you be looking at artifacts caused by squeezing the huge Adobe RGB color space into the tiny one of a normal desktop screen (unless you have one of nice and expensive ones)? I would expect this look to go away as soon as seen on another computer or printed.
