ET can't summon sealed soul cause it's mechanics involves summoning of the soul from the Pure Land, so it can't summon a soul which resents somewhere else, although I don't know if Shinigami's stomach is the only kind of such a place. Izanagi doesn't include limitations cause it actually doesn't summon the soul aka space-time, but makes like it was just an illusion and the soul has never left the body.
