[argyllcms] How wide is the colour gamut covered by dispread?

I found out why my laptop does not profile well: it has a white LED backlight 
and inadequate spectrum.

At least I can calibrate it OK and there's no more blue colour cast. Colour 
temperature is good, tones are satisfactory, everyday colours (mixtures) are 
reasonably OK but pure colours are off, red looks orangeish. The colour 
spectrum of the white LED backlight in my display can't make pure red and the 
gamut of this display is surely less than sRGB. BEWARE! My old Dell with CCFL 
backlight has better colours!

Anyway, I notice that Argyll uses very many color patches. Can dispread profile 
wide gamut displays, like an LCD with RGB LEDs? How wide is the gamut covered 
by dispread? NTSC? AdobeRGB? How does dispread handle reduced gamut displays 
that can't generate pure R, G, B as per sRGB gamut? On my "crap" display it 
seems to oversaturate, trying to make colours that are impossible.

I think I'm finally learning how to use Argyll, it's a great tool.

Cheers, Stephen.
