I know about CVD and have read this article. The applications listed are mostly related to cutting bits and actual diamond. It says notably: "[some nice properties] would make it a nearly ideal non-stick coating for cookware if large substrate areas could be coated economically." If coating cookware with it is economically infeasible, I imagine coating a screen would be pretty expensive too. Which is why I doubt the iPhone used this and would like to know where that info came from.
