I’m looking for a list of differences, audio and visual, between the theatrical version of The Force Awakens and the Blu-Ray/DVD version as well as a similar list of differences between Rogue One’s theatrical and Blu-Ray/DVD versions. Could anyone give me or point me to such a list? I’ve sifted through a few pages of old threads here on this forum, but I haven’t encountered anything definitive other than a few unsubstantiated claims about The Force Awakens. Among the purported differences I’ve seen are

BB-8 making a bleep-bloop sound in his closeup shot during Rey and Finn’s escape from Jakku
a difference in the flags in the establishing shot of Maz Kanata’s bar on Takodana
the female alien spy in the bar whispering audibly instead of silently
a different credits sequence wherein the music is different (I’ve heard something about the Oscar consideration soundtrack) and the credits sequence is extended by three minutes

I haven’t read about any such differences for Rogue One.

Can anyone confirm or deny that such changes exist, along with any others I may not have heard about? Can anyone tell me where to obtain a copy of the theatrical versions of both films? Any help is appreciated. Thanks!
