Dual-illuminant camera profiles without DCP in darktable

[priort (Todd Prior)]

Someone asked just that at one time…

Is there a way to convert the LookTable from a DCP-derived json file (dcamprof) to the more general dcamprof lut format?

With dcamprof you can convert a DCP file to a JSON containing the look table. Then, you can convert that json profile to an ICC using make-icc or json2icc. However, dcamprof does not construct an ICC LUT from the dcp-derived-json file – you only get a matrix profile. I have specific DCPs that I’d like to snag the LookTable from to make into an ICC profile since Darktable does not (and does not seem to ever intend to) support DCPs. dcamprof’s LUT format is very different, being based on the YUV …
