Quite how those numbers get converted into a contrast ratio I'm not sure, but it certainly does have a lighter white and darker black.

Still not quite paperwhite, but getting there!
(paperback paper is around 60-70%. Glossy magazine paper around 80-90%)

Combined, that is a 44% improvement over Pearl.
