Hmmm... Agreed that they're mostly 2D sensors, but apart from near-field the post-processing brain can use depth-cues to for us 'see' in 3D. Also, you don't see in 3D unless your head/eyes/target is moving, right?
You definitely get 3D from just having twin perspectives on an object. You get even more when moving your head.
