Hi Ben,

I'll bet a cup of coffee that what they're discovering in that paper at
colour-science.org is the degree to which different choices of primaries
diverge from
the actual observer functions.

All these RGB output spaces are just 3x3 transforms of XYZ. They have nothing
to do with primary spectra and observer functions.

My speculation would be more along the lines of wondering if a particular RGB
has a 3x3 transform that moves it towards LMS or a sharpened cone space.
