Why does iPhone 6 use @2x image assets?

iPhone 6 plus uses @3x image assets, but iPhone 6 uses @2x image assets - just like iPhone 4 and iPhone 5 (Image resolution for new iPhone 6 and 6+, @3x support added?).

iPhone 5, iPhone 5C and iPhone 5S have the screen resolution 640x1136. The screen resolution of iPhone 6 is 750x1334.

So iPhone 6 will scale up images from 640x1136? Is there any way to make graphics customised for iPhone 6's slightly higher screen resolution?

Edit: I know that the PPI is the same. But say for example I want to have an image take up all available width on both iPhone 5 and iPhone 6. I create a 640x200 px image and name it [email protected]. On the iPhone 6 it's going to be upscaled to 750 pixels width, no?

iPhone 6 uses @2x image assets and not R4 or something else because apple didn't provide suitable APIs for background images!

The most direct way now is to create 2 assets and programatically load them :(
