Every set varies slightly, so what is the right numbers for one display may not be for another. Also professional calibrators will put the set into service mode (or ISF mode), and use a colormeter to adjust the gray scale tracking. This can't be done from the "setup" menu, nor by eye, but is required to get that last tenth of image quality from a display.
I know for a fact that Pioneer does adjust the voltage drive for each panel individually in the factory (and this setting should never be changed if you don't want to drastically shorten the life of the set). That alone makes one set's calibration numbers not applicable to another. Although, the main settings menu is rough enough that the generic settings you find for that will be right (or at least within a click).
