Wouldn't that logic imply gamma=1.0 workspace to be even better?
... 256 useable values! Working space gammas greater than 2 are said
to be more perceptually uniform. Perceptually uniform would recognize
the difference between (as you say) "useable" values and useful
values. That is, if you can't perceive the difference between the
values, or if your perception of their difference isn't uniform, how
useful can they be? But I won't take that argument to an extreme
either ... I imagine ColorMatch to be as useful for many editing
applications as is AdobeRGB. I wouldn't "flip a coin", ... either
might suit a particular need (slightly) better than the other.
