Eh, doesn't explain the difference in the curvature of the desk directly below the lamp or the difference in the chair or white thing below. Though I'm still with my reservations about it.
Wouldn't such warp be accounted for in the glass reflection of an iphone? How would one determine if the warp came from modification or inherent quality in glass?
I don't think that's possible.
Though I don't deny it may well be a possibility. Determining such a thing is extremely difficult.
