Yes, agreed. None of that relates to the HTML5 specification, though. 
CSS3 and SVG are separate specifications. I'm involved with both.

CSS3 Color did at one point have a way to override the ICC profile of an image. This was not implemented however, and was dropped from later versions of the specification.

SVG 1.1 has ICC profile support, but it is optional (in other words implementations are required to parse the syntax but are allowed to use the sRGB fallback color).

SVG Color is a separate module and makes ICC profile support mandatory. It also makes supporting the ICC profile in a tagged image mandatory (amazingly, this was not previously called out as an explicit conformance requirement; it is now).

I will be at LGM and would be happy to discuss these specs and related issues about ICC and W3C.
