The printer just takes RGB data, not gray or ligh cyan or....the split of the RGB data into the additional ink colors gray - violett, light cyan,...... happens internally in the driver, and the user does not have any control over it. Gray is a color like any other for the printer. You would need to go for a RIP which would let you use more ink colors in the profile generation process, I think i1Profiler would support that. The user cannot even control the amount of black, you would need software like a RIP which bypasses the driver internal color translations, Printfab would let you do that with black - UCR - Undercolor removal.
I did another test with the 720 or 702 patchsheets as reported above - running the test on the Netbit paper - on a Epson T3100X 24 inch printer which runs with 4 colors CMYK and with pigment inks .
I'm getting a total average of DeltaE's of just 1,33 over the 720 patches, and the value for the largest outlier is just 4.16. None of the gray patches are in the upper 10% of delta values. This means that both profiles are practically identical.
