I’m not sure that 1980 counts as a Retina-class display. IIRC, the player has reported 72dpi for desktop screens forever. I think you can also get it to report 120dpi in some cases, but I don’t think they’ve tried to introduce useful screenDensity except on mobile devices. You can try filing a bug at bugbase.adobe.com and see what they have to say. They could have changed something else recently that I’m unaware of.
