That is not exactly correct.
The monitor validation procedure uses one of two methods, depending on the software package:
1) It starts off with a list of RGB numbers, looks up their corresponding Lab values once the monitor profile is assigned to them, registers the Lab values read by the colorimeter from the monitor for each patch, compares the measured Lab values to the Lab values expected from assigning the profile, and finally derives DeltaE values from the comparison;
or:
2) It starts off with a list of Lab values, converts them to the monitor profile, sends the resulting RGB values to the monitor, registers the Lab values read by the colorimeter from the monitor for each patch, compares the measured Lab values to the Lab values in the original list, then finally derives the DeltaE values from the comparison.
