The screen's nothing close to Retina Display quality. "Retina" was coined by Apple, and refers to " high enough pixel density that the human eye is unable to notice pixelation at a typical viewing distance." With the iPhone, the target pixel density is 326 ppi. The Lumia 620 has a 3.8" display and a resolution of 800x480. Its ppi is only about 245.5, so it's way behind.
However, what you said furthers a belief that I hold. In my opinion, it's all just crap. No, I don't mean that pixel density or resolution is crap, but it's not something people really pay attention to, at least when the majority of users are discussed. That you see something that is statistically far behind "Retina" density as just below it in quality just makes me believe harder that the whole discussion and phrasing of the matter is pointless. You either like the look of the display or you don't, plain and simple.
