For the longest time, FBReader did no processing of images at all. It just centered them and displayed them "as is" - no dithering and no rescaling. I don't think the standard Desktop FBReader does dithering even today, but it does rescale images that are too big to fit on the screen. Have you tried images that are smaller than the available screen resolution?

I am not convinced that nearest neighbor dithering can produce artifacts this bad unless the original image was very small. So perhaps Pocketbook's FBREader is also magnifiying images.
