I was not thinking about archival purposes, point taken. You and Anton are right, this is a whole different can of worms.
Out of curiosity, why are 1D LUT and 3x3 matrix not enough for IDTs? This approach satisfies “linearity” condition.
In my mind (and mind of a lot of my colleagues) ACES is an established color-management system with its own set of pros and cons. There is some mental inertia which we should overcome to pivot it to a meta-framework. It is a very interesting challenge, especially because some of the concepts should be defined from ground up, but I wonder…
What specific problem(s) does meta framework solve? I don’t see a lack of innovation in the industry, but I may be missing something.
P.S. I think that the latter part of the discussion can be continued in the framework thread.
