Darktable can't handle discolight?

Yes, a LUT ICC camera profile, made with SSF data I can’t share right now, from as-yet unpublished research.

Being able to set a good input profile seems a very good first step to take in this case. I still find it strange that darktable is limited to the, somewhat, simple ICC profiles if you want to apply an external one and not the more sophisticated DCP profile.

ICC profiles can do the color transform with either a matrix or a LUT. But yes, they don’t have the information to do the color temperature interpolation…
