Well, no. The colour you get with "porocess cyan" depends on the ink set, paper,
printing process and lighting. There is no magic about a mac that lets it
know all these thuings.

What you are running into here is the inherent device dependence of
RGB colour specification.

Note that with the primary and secondary colours, each of RGB is either at minimum or at maximum. Thus (uniquely) gamma correction or the lack  of it does not affect the colours.
