Question on upconversion; is it cheating?

Digital Drive

Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

As I understand these digital upconverters (such as the dcs),
they use an interpolation function to generate a high freqency
data stream from the standard 44.1 kHz CD data stream.
If my understanding of the process is correct, something seems
philosophically wrong with this to me. It is easy to believe
that there may be more detail and a sujectively better sound,
but it does not represent the real high frequency signal that
existed when the recording was made.
It seems like colorizing a black-and-white photo. Yes, it makes
the representation more "real" since the world is color, however
the photo does not represent a scene as it ever existed in the
world.
Am I wrong about this? Or is this a worry that others share?
I have never heard an upconverter so this is just theoretical.
