Apples iTunes Extras feature has always been extremely limited, but thats just changed. Before, only iTunes on the desktop users could view extras that came with movies that were purchased from Apple; Now, as part of iTunes 11.3 —which went out today — along with a push to Apple TV users running the 6.2 version of the software (which was released last week), iTunes Extras will show up alongside any purchased HD films. Apple is also opening it up for movie studios to add additional content at any time, and for free.
