Because they are a better transfer than the crap 2011 versions
This exactly.
Granted, we’re talking about niches of niches here (people who prefer physical media, prefer that physical media to be blu-ray, and people who care what version of Star Wars it is they own on physical blu-ray) but just in case you’re a Star Wars fan who wants an official release to look as good as possible and isn’t interested in either Disney+ or piracy - these blu-rays are the answer.
