I would like you to provide a better source than a marketing page which
does not necessarily use 'modem' in the context of 'mpss remoteproc'

The easiest test to conduct is to boot up the device and run qrtr-lookup
with and without the rproc.

Or actually, if the rproc succeeds to start up, that's proof enough that
it's actually there..
