"the illusion only really works when you keep looking the same way, lighting is baked in, so is specular and everything else. the texture also is not "calculated" on the opposite side, it is just projected through the mesh."

It's illusional that one day we'll be able to create 3D models out of 2D photographies with a certain quality. The terms already says it, 3D -Y 2D == information lost. The only way such things could work would be to have a camera that stores depth informations in the picture combined with a tools that allows you to get the specific location of the camera. Several shots from different sides, and voila.

Everything else are just dirty hacks which will always have their nitpicks.
