That artwork isn't final. Yes, GODZILLA RAIDS AGAIN is 1.33:1, not 'scope. If you want to get nitpicky, MOTHRA VS. GODZILLA isn't "Cinemascope" either, it's Tohoscope. It's the same technology and the same aspect ratio, but the name "Cinemascope" was, I believe, copyrighted by Fox or the developers of the original Cinemascope lenses.
