I assume they only did it to explain why the DVD cost more than the VHS you might already have. Even with Redbox you probably didn't have the DVD long enough to get a chance to watch the extra content.

I am very annoyed by this with the recent surprise smash hit of the movie 'Obsession'. This is a new director made popular by his devoted fan base and they just announced the blueray. One director commentary, a tiny 'featurette' and then just the film.

I remember back in the heyday of physical media(2010s) directors like Edgar Wright took curation of physical media extremely seriously: Multiple commentaries by not only the director but with the cast, production crew, sound designers etc. Deleted scenes, multiple featurettes and even picture slideshows.

I wonder how much the design of Blueray menus is hampered by the tech choices used in the format. DVDs were video files that repeated with tiny overlays that the player would just draw. Bluray seem to be entire Java applications of which most studios develop one generic version and reuse for every release.
