So expect that as long as Amazon continues to insist on using such a lighting layer there will be a degradation in readability of the eInk screen. Even without the splotchiness and/or discoloration, an extra layer of plastic will blur the eInk screen a bit. No plastic is perfectly transparent or invisible.
Yes I agree that the light layer is poorly designed and implemented in all the PWs, Voyage, and I assume the Oasis as well. I wish they would offer the Voyage without the light layer, though I know they never will. I would rather Amazon improve the physical quality of their basic Kindle with higher resolution screen and better ergonomics instead of focusing on a bunch of firmware features that I could care less about. Most of those firmware features are there because it helps Amazon to sell you more books.

There are, however, many devices with uniformly lit devices, for example, I've bought and in imported two Kobo Aura H2Os from Canada chapters indigo with absolutely uniform lighting both times, every time, and I'd be willing to wager that if I bought a third it would be uniform too. How are they able to get their devices looking normal? Luck of the draw?
