And aside from lacking the improvements you mention, I find the ICCs we're currently making to be pretty inadequate.  If set up an ICC transformation and compare it to the original LUT, there are usually noticeable differences.  It's in the ballpark, but often not good enough for production work.

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?
