Does the iPad Air Use Retina iPhone App Assets For iPhone Apps?

[BergerFan]

I'm testing this using the Fight Night Boxing iPhone game, from EA, which is retina on my iPhone 5s, but distinctly low-res on my iPad Air.
The same game was hi-res on my older iPad Mini(which I sold).

iPad Mini is 1024 x 768.
iPhone is 1136 x 640.

The game looks "high-res" on the non retina iPad Mini because the resolution is similar with the one on the iPhone, but an iPad Air is 2048 x 1536, which is pretty far away from 1136 x 640. Thats why it looks pixelated or low-res.
