I assume one of the biggest problems is, that both eyes see the exact same image while in a „real 3D environment“ both eyes would see slightly different views of the world where the brain then reconstructs the depth out of it. Here we have the „mono“ version with some „fake stereo“. It works surprisingly well, but the brain calls the bluff.
