Ray,

Yes. We all agree here.

The 9th?

True.

Why not just quote a single "gamut" metric? DeltaE cube or something
similar? If that's all Daniel is after. This is simple enough to do with
ColorThink, ICC3D, Monaco GamutViewer, Imatest GamutViewer and I'm sure a
few others I don't personnally know about on the internet.

So true. A single metric that we know convey mathematically the sheer volume
size of a three-dimensional object would not be enough? Obviously.
Ray, you're on the money -- again.

So, like everything else in life, it's a matter of compromise :(
Can't have a cake and eat it too.

I guess it could be, as a first order approximation of some kind. What
purpose would it serve? Well, for sure, we can say that a newsprint gamut
metric would unequivocally convey the idea that the corresponding device is
rather a cramped space. But, at the other end of the scale, all the large
format inkjet printer would gravitate around a more or less tight cluster.
Which among those LFIP would be "best" would be a job opened for some more
qualitative kind of gamut metric, on that would depend of preffered color
reproduction and appearance. [That would be most interesting]. Incidently,
doesn't the CIE have some kind of crazy TC working on this exact idea these
days?

Right.

I'm with you.

That gloss component must have a surprisingly large impact of our perception
of depth and colourfulness (as in Robert Hunt's colourfulness (plénitude de
couleur, in french). It's hard to avoid it in the case of utmost color
gamut.
