Thanks guys !
Just to wanted to mention about the architecture thing that I found this old message by Daniele from the Gamut Mapping VWG :
I think Gamut Mapping and compression is an essential part of a successful image processing pipeline. It is needed in a different context at different parts of the processing stack […]. So further gamut compression might be needed to prepare scene-referred data for further display rendering (very close to the end of the scene-referred stage (maybe within an LMT)). […] After display rendering, we might need further gamut compression to produce the final image on a given display gamut. However, if the scene-referred data is already sensible, gamut mapping on the display side is not that big of a problem in our experience.
And since it is not the first time I hear about two-stage gamut mapping, I was wondering if this be should reflected in the diagram/Miro board.

PS : acescentral is full of these little hidden gems that I find fascinating to dig from time to time…
