Try lsmksysb.

If your mksysb is in a file use

lsmksysb -lf /path/to/mksysb_file
and/or
lsmksysb -Lf /path/to/mksysb_file

For an mksysb on tape use /dev/rmtx instead of the file path.

Adittionally you can use

lsmksysb -Vf /dev/rmtx

With lsmksysb only the various tocs (tables of content) are checked and displayed.

A slightly more thorough method is using restore (I assume it's a file, not a tape):

restore -Tqvlf /path/to/file

This will access every file's header, but will not read it as a whole.

A byte-by-byte check can indeed only be achieverd by running a restore.
