The very first version of star wars has never been on home video. However the second version with a new hope has never gotten a new transfer after 1993.
Empire and Jedi also are stuck at 1993 4:3 SD letterbox.
They spliced on a nice clean version of the original crawl in 2006 to make the Star Wars DVD original but it still was the same Definitive edition transfer afterwards.
The 2004 cut is no way better than the blu ray. And at least the blu ray is not zoomed in like the spike TV version.
Has some fixes but also worse new cgi alterations and Vader yelling noooo in return of the jedi.
Basically the blu ray is a lazy tweaked 2004 from the same 1080P locked master.
Would have been nice to get newly transferred versions of the films of all versions for a master set or just the original theatrical versions for the folks who don't want anything else.
