The measurable brightness difference between the white is 0.02%, and 1.63% for black. To put the differences into perspective, attached are the 2 rendering using the closest matching RGB values. The difference is so small that I doubt anyone could reliably tell them apart in real use.
Which led me to believe that people who claim to have noticed huge varieties in terms of the screen quality on the K4s either had very bad luck, or simply being tricked by the difference lightning(few inches a part and just a tiny angle shift makes a big difference!). Of course I've only measured 2 out of the millions produced, but if they are so inconsistent, I must've had incredible luck to pick out 2 of them that are so closely matched, and both of them have greater contrast than the K3 I've tested.

Okay where do you buy yours from?
I am one of the unlucky ones. I had one come from KY and GA Amazon's warehouses. Neither are good as my K3.
