Never say impossible, Rob.
Some people do have perfect color sense, just as some have perfect pitch. Both
are rather more uncommon than most folk think. But when your electronic
calibration system does not agree them, it is your system that needs
calibration.
Relative color sense, like relative pitch can be learned, but may be thrown off
by adjacent color casts. The perfect senses seem to be innate and cannot be
learned.

Color perception is a relative and subjective thing, if you use a

grays on your monitor will not look gray to you, would this be a good
thing?....
I didn't add that I have several profiles, one which is set up specifically to
match the colour temperature and luminance of my reference light source (which
I also measure with my hardware, Spyder2PRO). I can tell you quite honestly
that when I get my prints back from the printer and compare them to my
calibrated monitor profile viewed under my reference light I can tell if the
printers equipment is out of calibration.
It is impossible to set up a colour managed work-flow with the degree of
accuracy my system provides using a software calibration tool. My monitor is a
top end version and even contains a pre-set sRGB profile which pre-sets colour
temp, gamma, luminance and contrast relative to the sRGB spec, you would be
amazed at how far out that is too, the hardware calibrator just manages to get
it into spec via LUTs.
Carry on with your software cal tool if it's working for you but don't suggest
that I don't know what I'm talking about, it's impolite and offensive.
