My take is "designed for Immersive Video" in the sense that Apple's format has very high specifications, and most other HMDs do not demand 8k per eye or 90fps.

This camera meets the minimum specification for the Immersive Video format, but that doesn't mean you wouldn't also be able to render the output to other formats.
