It is not quasi, it is just branding. It is not BS, just a clever name with specific meaning—which is more specific than "high DPI". Where exactly does high starts and middle ends? DPI does not take into account viewing distance, because it is all about linear measurement. "Retina" is about angular. If is is smaller than average eyes ability to resolve then it is retina, what's BS about that?

"Retina" is just as ambiguous as "High". Apple didn't invent anything with "Retina" screens so branding is pretentious, pixel density is just that: a number.

[taligent]

No. Retina means that you can't distinguish pixels at your normal reading distance. A number is meaningless without understanding the technology.

And I wouldn't downplay Apple's involvement in the Retina displays. Their prepayments allow for companies to do R&D/production.
