I would return it and wait for the next Kindle Paperwhite. The fact that you can no longer buy the WiFi Paperwhite on Amazon is probably a good indication that a new one is coming in a few weeks.
I will assume, based on complains of blotching and such that the new Paperwhite will have improved lighting...more even, less blotching, a year of tech refinement, etc. Although to be fair, I think the current Paperwhite is just fine.
