I may be missing something, but it seems as though the information is useful because, in an ideal system, at least, there should be a direct relationship between the primaries and the gamut of the device, at least at those three corners, with some logical extrapolation as to where other gamut edges might be. Right?
Right; various steps such as adjusting primaries to the target whitepoint at the video card level, generating the inverse table used by analysis software, etc... all have useful purposes in calibration and profiling, but they also are extra layers between the display's actual gamut and our view of that gamut. Monitors are, in many ways, quite linear devices, and simply knowing the raw color values of the primaries tells you the most fundimental information about that display's gamut. Is the green brighter than that of a Cinema Display? Is the blue deeper? This is how I have always compared one monitor to another in terms of what the phosphors (now LCD colorants) are capable of.
The profiling software might, due to its own logical flaws, reduce the available gamut when the display is assigned that profile, but comparing the raw primary data seems useful in terms of an apple-to-apples comparison.
Flaws, perhaps, but also intentional adjustments and ICC simplifications. Whatever they are, its worth comparing values outside that system as well as inside. It would be a shame to damn the gamut of a monitor based on your particular sofware or the workflow you use in running it, and assuming that is intrinsic to the monitor. It would be worse to compare apples to oranges, through some software based gamut limiting that one package or workflow applied and another did not, and come to an erronious conclusion about how two monitors' gamuts related to one another.
In other words, understanding the raw primary data and understanding the calculated gamut via different profiling workflows would all have their own stories to tell, both about the device and the workflow elements. No?
A well reasoned viewpoint; thanks for sharing it.
