Yeah, I think in my case, I might compare the "length" of the Contents stream with the XObject stream (and see if they are drastically different -- I know with compression they would never be identical).
In fact, I guess I could also check the /ProcSet for the /ImageB tag, and it's likely that there will be only one /XObject with a stream in it as the image of the whole page...
