That's still an awful way of doing it.
Cubic delta E in CIELab is a more modern measure of gamut volume,
rather than 2D plots that conceal what's really going on.
So a usable measure would be the volume of the device gamut
intersection with the target gamut, as a percentage of the target gamut
volume, in CIELab space cubic delta E.
