What I wanted to say is simply: You should not ignore these tags completely, since they are accidentaly very powerful. E.g. changing the whitepoint with a vcgt tag is fairly easy, so don't apply it and all data contained in the profile is invalid. You are right in terms: it's the responsibility of the OS to apply these changes. But there's no better/cleaner way for now to say that certain calibration data lead to a certain profile (at least it's the impression when looking at all the commercial profilers).
