    Shalom @3zero3 long time no see :)
    Agree, dmg file (InstallESD.dmg) is a compressed file - ZLIB.
    In theory, uncompress first and then create delta(s) would work but you would lose original checksum unless you use correct algo and params to compress file again.
    And very likely you need to do this in a Apple OSX environment, to read all files.

    Correct me if i'm wrong, Apple is not my strong side.
    :)
