Just sRGB? I was under the impression it could be used for all color
transforms (to print etc).

Good deal. I just heard from X-Rite that so far, their product do not
support this. So the question is, what's the advantage and can one 'see' it
on output? My understanding is the use of this tag 'reduces ambiguity' for
end users since now there is a rendering-rerendering color space for
conversions that is well defined. I was also told that the difference in its
use versus a non defined (well non defined to the user) space might be quite
small. So while I can see the benefits in reducing ambiguity here, is this
helpful to the end user?
Ideally I'd like to test the differences and see what effects they produce.
Can this be done today? It sounds like Argyll can.
TIA
