There is a bigger "tell" here. A clear case serves no purpose beyond being "a case". It doesn't offer any particular inherent personalization. But what it DOES say is that Apple has finally decided to forgo their nonsensical "holdout" from their position that a case isn't necessary. Every survey shows that the gross majority of users put cases on their iPhones. And the drop tests prove that the iPhone isn't especially hardened by design (especially when compared to the competition). So a case IS NECESSARY. And THAT is why we got the camera "bulge". Apple has remained completely tight lipped in the face of a lot of criticism about the bulge, with a few exceptions trying to paint it as some "inspired" design idea. But that's obviously bull. The "bulge" exists only to push the lens out past the edge of the case that caused interference with the sensor's angle of vision (which first started to be an issue with cases on the iPhone 4, into the 5 design). Basically, Apple engineered the iPhone 6 (and later models) with a bulging lens protuberance because they KNEW users were going to put the device in a case; it had nothing to do with available depth in the shell for lens/sensor thickness.
(And they obviously "know" this because they know the iPhone design just can't be engineered to overcome its inherent fragility due to the materials demanded by the Design team. Glass, aluminum, and stainless steel are simply not shock *absorbing* materials, certainly not like TPU polymer. In short, Apple is selling a fragile phone using a PR message of "beauty" while obviously cognizant that the beauty needs to be covered to be long-term usable. IMHO, true design and engineering "beauty" is when the beauty is kept intact AFTER the fragility problem is mitigated. Could anyone imagine the laughter at Samsonite for selling "beautiful" luggage that required being placed in a Pelican case to be put on a plane?)
