Ideally, yes. However there can never be any certainty that all versions were handled and processed identically. In the comparison we did listening to the DVD tracks of the movies we watched, there were very marked differences between the DD and DTS tracks that could not possibly have been due to the differences in their compression alone. Also, from a cynical marketing perspective, if people couldn't hear some difference for the money they spent, they would question the expensive of the format.

In the instance of the comparisons to the master I have, I know with absolute certainty how the files were handled - I did the mixing and mastering myself.
