Would something like an Oculus Rift VR help reduce the number of projections from being "4D->2D" to be "4D->3D"?

No, Oculus Rift's screens are still 2D surfaces.

Sure, but at least you get stereo vision and headtracking that makes it less obvious you're just looking at a flat screen showing a mono projection?

It might help mentally, but it won't reduce the number of projections. You'd have to be able to see every point in the whole 3D volume, not just the surface.
