I'm intrigued by your comment of not good enough, when I compare, the differences are usually most visible as a slight lift in the blacks vs Nuke.

We set up with P3 monitors and generate profiles using the displays' profile typically with a log input colour space with some wide primary set, e. g. ACEScc(t).

What sort of differences do you see?

I'd say lift in the blacks is the most common, usually shifting their colors some direction in the process. This is exacerbated by us making profiles intended to be applied to a log image, so you lose some bandwidth there.

The differences often don't seem too major, but I'm usually making them for Matte Painters who have a VERY good eye for even small shifts.

It's hard to tell how much of it is non-optimal profiles from OCIO vs. limitations in the CMS software vs. limitations in the ICC approach overall. Maybe Lars can help us get to the bottom of it.
