They don’t have the benefit of knowing all the differences we’ve uncovered beginning with the Italian tv recording. The Laserdisc is probably the 1978 reissue version.
The (widely available) pan & scan VHS is the same cut of the film as the letterboxed laserdisc and VHS. Except the letterboxed version has an anachronistic Warner logo and altered colour timing. You don’t need to be a member of Original Trilogy to know that laserdisc isn’t the original version of the film.
