Like call-process, call-process-region does not support remote
directories. As you say, there is process-file, which does this with the
same arguments as call-process.

tramp-call-process and tramp-call-process-region are internal
functions. Their docstrings say clearly, that they are based on
call-process and call-process-region, respectively.

What you are looking for is an implementation for
process-file-region. That does not exist (yet?), AFAIK.
