I don't think that's been definitively established yet (there are some who think its appearance is the result of a mystic upgrade from Dr. Strange). Regardless, your theory does bring me back to what I find problematic with the AI and other high-tech features Tony built into Peter's suits. He's not wearing an armor-plated IM suit, so as often as he gets knocked around in battle one would expect that underlying tech would get damaged and become useless. I thought it was OK for the Iron Spider suit in IW/EG, but beyond that one I think he should just have a normal suit and his web shooters.
