VVE tables are explicitly excluded from the calibration comparison routine. The documentation explaining why they are excluded is a "bit terse" (programmer speak for non existent). If I recall, it is because the comparison is done at the raw hex level by comparing the raw hex data in both files. Because the VVE tables have no raw hex data in the file they are not compared. That will change in V8 because comparisons in V8 are done at the calibration data level instead.
If you generate coefficients from the modified VVE tables, then the coefficients tables will show up as different.
