[css-media-queries-4] color-gamut contradiction of UA vs output support

[gregwhitworth]

Looking at the color-gamut CSS property there seems to be a contradiction between that of the propdef and the definition of the color spaces themselves.

The color-gamut media feature describes the approximate range of colors that are supported by the UA and output device.

This seems to contradict the definitions of the color spaces:

The output device can support approximately the sRGB gamut or more.

There will be scenarios in which the UA can render a specific color space but the display output cannot and vice versa. I think the Note following the propdef normative text is trying to get this point across but it would be valuable to understand if this MQ is stating either:

1. The UA & the display output can support the given color space
2. the display can support the given color space.

It makes sense to me that it should be option 1

Yeah, it's option 1.

I'll fix this now.
