Agreed. I got fooled because ghostscript actually tries to maintain the source PDF's encoding method for each image, and because of that, I thought it was just replicating the original image's object data stream from the source file, but apparently it is not. As you said, if the image is lossless to begin with, then there is no impact to re-encoding.
