Pointer's Gamut check
I would love to see some sort of Pointer's Gamut check to make sure that albedo textures belong to real surface colors.
It could be implemented in Legacy and when using ICC profiles as some kind of preview mode in the 2d view (like Esteban mentioned)?
Here is a link to an article about Pointer's gamut : https://www.tftcentral.co.uk/articles/pointers_gamut.htm
And a pdf to explain a bit the tool and its purpose.
(sorry for double request, one for each software)
