I'm not sure I understand what you're asking for. The picture quality of a brand new Eastman Kodak 35mm release print in 1977 would exceed Blu-ray quality in some areas and come close in most others, even in a crummy cinema.
Are you looking for the appearance of a very beat up print shown as part of a mid-80s revival on an out-of-focus lens in a terrible underground theater?
Star Wars didn't look that way in 1977.
