How would an umpire, on the field during live action, have any idea whether the BU "chose to pass on" or simply "did not see" the obstruction.

You see it you call it. I grant that as PU and 60-90 feet away, the OBS needs to be a little more obvious to be called - but if you see OBS - whether PU or BU, you call it.

Like I said, I suppose this may be regional ... I would never take umbrage at a partner PU that called an OBS on the bases. OBS just takes an instant, and it is usually away from the play - there are a huge number of reasons a BU could miss an OBS without doing anything wrong.
