I then imported and aligned the photos in Pixelmator and cut bits out if needed to best show off what differences there were.
It seems the new unit's black is noticeably darker, really visibly in the "Slide..." photo. But the "Kindle" photo also seems to show that the white is darker too. Sure doesn't look that way when placed side by side though -- it looks much lighter. A contrast effect of the sharper black? Either way, it looks much clearer.

Did you disable the automatic iris or other settings that could affect the differences? Some digital cameras also auto white balance, which could affect the differences.
The biggest difference is that the kindles need to be "exercised" to warm up the dark oil in the beads, and to detach any white zinc oxide particles from the bead surfaces and break up any white clumps. Also, the default eInk display driver waveforms are tuned for 25 degrees C, so the kindles should be warmed to that temperature before any accurate comparisons can be made.
You need to do multiple full flash updates after the displays have warmed up, and THEN do you comparison photos.
