Now's the time to make better ICC profiles ?!

The current set of ICC profiles (I looked at the ones created for ACES
1.0.3) has some short-comings in current workflows and that we should
consider addressing. Here's my list:

- The PCS space is Lab. This is too small for current projects. Lab is
smaller than Rec. 2020. Several corners of the 202 cube get clipped by Lab.

Whilst I'm don't think OCIO has perfect ICC support, I'm not sure
what you propose is even possible. Last time I read the ICC
specifications the only options for profile connection space are
L*a*b* and XYZ, neither of which have any limits which prevent you
using 2020 gamut - I certainly have profiles using ACES AP1 which is
wider than 2020. Could you describe what you are trying to do?

As a random guess are you perhaps relying on the inbuilt sRGB display
profile, when really you need a wider one?
