In order for us to be in a void that affected how distant supernovas appear, it seems the void would need to be large enough to encompass many galaxies. Otherwise, we would see all supernovas as uniformly more distant. If the gravitational effect is primarily an edge effect, then we do not need to be in the exact center to see a uniform effect. However, if someone is looking for the effect, it seems that they should be able to find where the boundary is with enough data.
