I see no way around all that optics physics not sucking up computation and battery. Perhaps Apple will add liquid glass silicon to the mix to do that physics in hardware. Using glass to compute glass, LOL
Liquid glass can't possibly be that much more expensive than vibrancy (if it even is). The refraction effects are effectively just a displacement map (probably calculated realtime, but still).
I'm not sure I'd want that on my daily devices, however I would like this on my car heads-up unit where tactile feedback with actual buttons is preferred to keep the eyes on the road. At least that would be better than nothing.
