Good job with CBDL, a favorite function of mine.

I have an SD9's X3F meta-data which includes 3x3 color matrices for cam-to-XYZ and WB correction. Also includes a 4096-point LUT but which I think is for linearization. Can put them up on my site if you're interested although I'm not sure they would be helpful to your purpose.

For DIY profiles, one can use the Adobe DNG Profile editing stuff.

Particularly see the first illustration under "Overview" ... just what the Doctor ordered!!

In there, one can mess with a 24-patch card image to produce a type .dcp file of choice which can then be used by editors such as RawTherapee. One could also shoot the card with the SD9 and not edit it - just output a DCP file (*.dcp) and see how it looks ...

Alternatively, in RawTherapee, there is a 3x3 color channel mixer which could be adjusted to get your desired result - and the type *.pp3 side-car file for those settings can be saved for re-use with other images ...

For example:

-- hide signature --

what you got is not what you saw ...
