There seems to be a total misunderstanding by many as to the ability to
just "look" at a waveform display of an audio file and deduce from this
its original sample rate if it has been upsampled.  The reality is that
this is not possible.  

There is no "fingerprint" that can be discovered in a downloaded music
file to determine if you have been tricked into buying an upsampled
track.

Here is our friend Bruce implying that he can do this:

"I'm finding more and more labels that take the RBCD layer and just
upsample it to DSD and call it an SACD. I've checked almost a hundred
today for HDtracks and over half are upsampled. Go figure....

However in reality there is nothing to check in an audio file that will
give you conclusive evidence as to the original sample rate of the
source material if it was upsampled.  You can't look at the file's
"properties" to determine its original sample rate.  You can't look at
a waveform display to determine its original sample rate.  Once an
audio file is upsampled, all traces of its original sample rate are
gone and even if you were the greatest audio engineer in the world, you
can't do it.

I am making this comment for these reasons:

1.  To correct misunderstandings.
2.  To emphasize over and over again that if you dare to spend your
money on anything represented to be "high resolution" audio, you are
doing it on pure faith and trust that the vendor is being honest with
you.

And let’s define for a moment what “honesty” means.  It means if you
are a vendor selling alleged “high resolution” audio, then you are
OBLIGATED to know the ORIGINAL source of the material you are selling
and HOW it was converted to a downloadable format.  And this
information needs to be DISCLOSED to the potential buyer.  If you don’t
do this, you have NO RIGHT to represent that you are selling alleged
“high resolution” audio.  And a vendor has no right to assume that just
because an album is available on SACD that it is high resolution.

Conclusion: Let the buyer beware!
