Obviously, there will never be a meld for binary files, which detects transpositions of identical blocks of data.  There is a vbindiff tool which shows a hex view with the differences highlighted.  The lion kingdom has long had a tool for showing locations of changes without showing the actual data.

For comparing disk images, you're more interested in equivalent sectors rather than bytes, so it takes a threshold argument to show differences by the sector.  There are still dreams of showing transpositions of identical data.
