If you can share the EPUB, that would be fantastic. If not, can you please just upload the PNGs (or plop them in a sample EPUB and attach them to the post).
Can't know unless you post the images... I wouldn't mind tossing it on my Nook and seeing how these specific PNGs react... and also doing much closer analysis of the PNGs themselves.

I recently stumbled upon some problems with certain Grayscale + Alpha PNGs here:

And also helping figure out some problems with 2-bit and 4-bit PNGs (which yours could potentially be):

As a side note: I have a sample PNG Test EPUB in both topics. Stick that on your Kobo and let me know how/if the Kobo displays all the PNGs.

As most images are a large white expanse with crisp black lines, I want to preserve this as much as possible.

I like the way you think friend (I too am a huge proponent of PNG)!
