Sounds good. Maybe you can give some thought on how a DCI P3
color gamut carried in a BT.2020 wide color gamut can be
automatically mapped back into a BT.709 (sRGB) color gamut ?
There will be a lot of need for that, because most UHD ("4k")
standards will be based on BT.2020 color primaries.


you can do it two ways, mechanistic (hard way), empirical (easy way)

there is a problem of "repurposing" a smaller gamut back into a larger
gamut, best to keep the original with profile information then just
"purpose" it again
