No, because pg_restore has logic to adjust the references to match the
new BLOB OIDs. If you have a test case where this fails to work, let's
see it ...

psql is out on a limb claiming that LOs can have comments --- there's no
support for that in the backend or any other client application. It's
doing it by direct manual injection of entries into the pg_description
system catalog, which is why superuser privilege is needed. It's a
useful hack if you only use psql, but still a hack. Feel free to
contribute a patch for backend COMMENT ON LARGE OBJECT support, if you'd
like to see a better level of support for this.
