To me the videos and stills taken with the iPhone are much better than those taken with the Vision Pro. The iPhone cameras are designed for photography and video, while the Vision Pro cameras are designed to pass the outside world through to your eyes. If you take video on the Vision Pro it looks like the pass through. Good (for pass through) but not great.Apple's iPhone immersive videos can be captured with a pair of lenses as well, it is just limited by the incorrectly small effective pupil distance of the iPhone's lenses.
Having the video match the pass through lets you do a neat trick. You can record someone in a place, and then come back to the same place later. As long as you stand in the same spot, you can line the spatial video up with the empty space where your subject stood and it looks like the person is really there, and you’re viewing them in pass through
