According to the official canon, the only canon version of the films is the 2011 SE. This is the case even for Legends, as this decision came down before the canon was reset

In short, the only releases with authority of any kind are the most current SE's.

Interesting that Spike aired the 2004 version. I think, however, that this was the most recent version licensed to media outlets.

Also, as to theatrical showings, from 97 til now any theater that rented a print for a showing got the 97se, because no prints were made of the 2004 or 2011 versions. Now, with the recent screening in Atlanta it is clear that there is a new dcp (Digital Cinema Package) that has been created from the 2011 master.
