Beyond fantastic. Well beyond.

I can see some cases where this is going to fall apart possibly? I
believe most 'agnostic' linear spaces rely on heavy granularity on the
input and output side of things to control how the data is to be
interpreted.

I believe Matt Ebb and Xavier Thomas probably have the most direct
ability to discuss this topic at length.

Fantastic.

This would imply the need for ICC display profiles as well, to provide
proper LUT mapping in the VGA to display the images properly, correct?

This is fantastic work and lovely news.
