Of course. Therefore, you can have a better contrast, while still have grayer text.
If the Kindle 4 has whites of value 140, and blacks of value 10, it's contrast ratio is 14:1. If the Kindle paperwhite has whites of value 225 and blacks of value 15, it has a contrast ratio of 15:1.
Its white is blindingly white, it's contrast is a tad better, but its text is still grayer.
I could see people preferring the Kindle 4 because of the blacker text, and maybe even because it's not so extremely white.
