Generally the principle of relativity only applies to a small enough
region of space-time as to be effectively flat. If you do have a very
large region you could detect cosmological curvature. This curvature
would be at right angles to a preferred time axis, which would imply a
preferred reference frame, the one where the curvature is not "bent".
Your privileged subset would be the people who were in this preferred

This is not really a violation of the principle of relativity though
because you just used too large a spacetime region. Detecting the
curvature of space near a gravitating body would be much easier and
also provides a way to distinguish one inertial frame from another.
