As far as I know NX still uses ICC profiles. Maybe they still can be extracted using this technique:

This works yes (or at least with the version of NX I have).

These ICC profiles expect that the raw file has been preprocessed in some way (applying some gamma etc), RawTherapee has this coded in rawimagesource.cc, but it was a while ago since it was tested last I think, but you get the idea.

So what I would do to replicate Nikon NX look is to extract those ICC profiles, and figure out how the preprocessing is made. Then I'd generate a new ICC or DNG profile which makes the same translations but without the preprocessing (will require some coding).

Then, that new ICC profile would be free of copyright and licensing issues ?
