Isn't it just the one report, really?
My K4S screen is as contrast-y as every K4B I've seen so far* -- which doesn't necessarily preclude better quality control, maybe I have a really good unit, but I still think it's a bit soon to say the K4B has 'consistently better' screens or that they have 'probably' switched manufacturers.
*even better after the 4.1 update, but that's just because of the font tweak
