Are you talking about the tape data being compressed inside the AWS image? Hercules has a format that does this, upwardly compatible with AWS, called HET (Hercules Emulated Tape), but I don't know of any other implementations of it. Each block is compressed after being received from the program writing the tape but before being written to the file and uncompressed after being read but before being returned to the program reading the tape.
