In the process you describe, the profiling software isn't aiming to make
any "corrections". It is merely building a description of your
printer/media/ink etc. combination. The text file has the relative ink
percentages you sent (which is the only thing you can tell a printer to
do - you can't send it a "color"), and your spectro tells the software
what color came out at the other end.
The "correction" would be done by the CMM when an application asks it to
transform numbers from an image in a different CMYK space into numbers
that will produce the same color on your printer as is represented by
the original numbers in the source space.
