We only have HD versions of the 97 Star Wars and Empire due to fan preservations. Not just the original but the 1997 cuts only exist on laserdisc.

Lucasfilm is only interested in the current version that would be the 2020 4K cut. Its funny how the 20th anniversary Special Edition is also not available on blu-ray.

Its ditto on theatrical Phantom Menace without cgi Yoda, it exists on laserdisc and fans did a 35mm preservation because Lucasfilm can’t be bothered to release the theatrical.

THX 1138 and American Graffiti are also probably a lost cause until some fan restores them. I’ve written Lucasfilm off, They are only interested in Disney Star Wars not in catalog releases of Lucas movies.
