When a light signal exchange procedure is used to infer spacetime coordinates of distant events from the travel time of photons, information about the photon's energy is discarded with the assumption that the frequency of light doesn't matter. It is also usually assumed that distant observers

has indicated that momentum space might be curved which would imply relative locality. To regain an absolute arena for invariance one would combine spacetime and momentum space into a phase space.
