It would seem that Ghostscript is saving the image rather than copying the binary data into a file. Saving a lossless image will essentially create the same image but a lossy image will certainly change if you create it instead of copying the binary. There are programs that know how to copy the binary. Also copying a binary does not require a license for the format.
