First off, major congrats and thanks for open-sourcing this as it's something I'm very interested in embedding in our studio.
Thanks!
That said, I was wondering if there was a way to create an ICC profile directly from 3DL or CSP lut? I think it's possible, but it appears to be somewhat constrained to the creation of a proper ocio config (which I'm still learning how to build).
Currently, no.
Both ociobakelut and ocio2icc require an ocio profile. However, it would be a pretty simple change to add the functionality to allow you to specify a single lut (or luts) on the command-line instead.
I'll see if I can knock this feature off in the next few days.
