This sounds like a case of a brain-damaged implementation on the target platform, as the PNG spec is entirely designed to do this sort of optimization.

I would imagine that ImageMagick uses libPNG and the behavior probably resides in there, you may need to build your own modified libPNG to force it to produce such images, I don't think this is an
ImageMagick problem.
