If the cals were superceded, the datastream should be the same with both masks. The dealer scantool (tech1) selects a data stream by year, make, and model entered by the tech. It knows nothing about the mask id and neither do techs operating it. Disassembling part of the car to get the ecm cover off and read the BCC takes too much time and since the only way to read the scan id is with the scan tool, scan id wouldn't be an option either.This would also explain why some guys get data with $85.adx and some don't or have problems. I have no idea what ALDL file to use to make a $D8 adx file?
