Do you own a copy of Colorthink Pro? Because you can print the target used to build the profile and measure it. You can load the reference data and the measured data and plot the deltaE in ColorThink which gives you the expected and then measured result of the profile to see how far off those two are. Its a useful diagnostic as a start evaluating the profiles.
That said, it is completely possible that the print behavior is very non linear and without some means to linearize the data, this is the best you’ll get.
