Retina scale factor versus display metrics

Richard, Thanks for the reply. But that does not really answer the question of wether the new mobilePixelDensity is actually based on pixel doubling (halving, tripling, whatever) or just of categorized screen sizes as my searches on the internet seems to be saying. 

In other words is the new mobilePixelDensity a true actual density of the screen or just a trick to group different sized screens into manageable groups and figure out a 'rough' screen percentage using DPI?

Also, on Android does this return Denisty_Low or ldli or does it return 0.75 ?

Thanks again,
