What would be the distinguishing theoretical differences between gravitons with an infinitesimal rest mass (non-zero) and cold dark matter?

Wouldn't they tend to have the opposite effect? The existence of dark matter leads to increased gravitational attraction. But if the graviton had a mass, gravity would have a finite range, and attraction between distant galaxies would be reduced.
