^^^Yup. Movie and TV sets and models are rarely built to be realistically proportioned. They're built to be practical shooting environments because the only important thing (nitpicky fans aside) is if it looks good on the screen and you can tell your story in it.
I know there are those who disagree with me, but after using the Photoshop perspective tool on the Jefferies cutaway it's more obvious than ever to me that the drawing is in forced perspective (even of the model Datin built might not have been). There are too many "tells" that are readily apparent to anyone whose done serious perspective drawing and worked to accurately scale details towards or away from vanishing points.
