I thought you meant the above applied to Kindles as well. I guess you did not.

On both KV and KOA2 the full color and 256 gray images look much better than the Forma and sw dither images, both of which start to darken well before getting to outer surrounding black ring and have other artifacts.

I'm assuming the problem is kindle handling of 4 bit PNG on KOA2 running fw 5.9.2. (Also, sometimes these images come up completely blank.) No time to do screenshot on KV and try conversion to 8 bit until later, maybe this weekend.

Much much better than photos, screen shots. (Stipulating that this is from a direct image view, not embedded in a book).
