Say something like this:
ESB DE 2.0 BD25: Just the Film
ESB DE 2.0 BD25: Just the Special Features
ESB DE 2.0 BD50: Film + Special Features + Bonus Commentaries
ESB DE 2.0 BD25: DocumentariesThe third one doesn’t have the Bonus Documentaries.
but it does have bonus commentaries as clutchins said. but your misreading has a point, as others may do the same. besides, the doc disc is not specific to a film, but is for the trilogy. but yeah, names similar to these should be somewhat clear?
