I think that the person that you're responding to was referring to the opposite effect.
On the K3 with lighted cover there's a brief "brownout" when changing pages where the light dims, which I never seem to notice when I'm reading, but notice a lot when my gf is reading on hers. My understanding on the paperwhite [which I've only seen mentioned, not in person] is that the screen blanking phase of refreshing causes the light to appear much brighter briefly, possibly equally annoying.
