Nope, it's 24bit, just like the BMP.

What do you mean with "special" settings? With your post in mind, I went and
checked my PNG, but somehow, I've got no paint-application (using Paint Shop
Pro 7 and XnView) to find the included gamma in my PNG. Nontheless, the
image gets gamma-corrected and I end up with banding. Though I can't find
the actual source for this problem (only guessing that its probably
calculating precision), it's reason enough not to use PNG, at least for the
moment.
