+
+ According to a StackOverflow comment:
+
+ The iPhone 6+ renders internally using @3x assets at a virtual
+ resolution of 2208x1242 (with 736x414 points), then samples that down
+ for display. The same as using a scaled resolution on a Retina MacBook
+ -- it lets them hit an integral multiple for pixel assets while still
+ having e.g. 12pt text look the same size on the screen.
+
+ The 6, the 5s, the 5, the 4s and the 4 are all 326 pixels per inch,
+ and use @2x assets to stick to the approximately 160 points per inch
+ of all previous devices.
+
+ The 6+ is 401 pixels per inch. So it'd hypothetically need roughly
+ @2.46x assets. Instead Apple uses @3x assets and scales the complete
+ output down to about 84% of its natural size.
+
+ In practice Apple has decided to go with more like 87%, turning the
+ 1080 into 1242. No doubt that was to find something as close as
+ possible to 84% that still produced integral sizes in both directions
+ -- 1242/1080 = 2208/1920 exactly, whereas if you'd turned the 1080
+ into, say, 1286, you'd somehow need to render 2286.22 pixels
+ vertically to scale well.
