Afaik the Vision Pro is projecting a point cloud and there’s a good chance that’s not dense enough for a single screw. Also, the VP is only trained on hands, so whenever you see someone hold a phone the phone is invisible and the hand occlusion is almost perfect there.

I‘m guessing it’ll be a long time until something as small as a screw will be properly occluded on Quest, which currently doesn’t have any kind of occlusion.
