In this situation, nothing.

This is done on outlets with metal faceplates because if the faceplate comes loose and falls between the outlet and plug (because of gravity) it will only hit the ground if the ground is at the top. If the ground is at the bottom the metal faceplate is live.

Again, as long as there’s not a metal faceplate there’s no difference. Typically, upside down outlets with plastic faceplates are used to tell you the outlet is controlled by a switch.
