I think it’s also worth remembering some people will want the best possible presentation of the Prequels, and even though the D+ versions aren’t as different - they’re still a better transfer than the 2011 blus, correct?
But yes, when it comes to this place and starwarstrilogy.com - it’s probably much more likely that these sets’ quality is only of note in regards to its utility for making better fan restorations. My interest in the set was primarily for the opportunity to get really good extras, and once it became clear that opportunity was going to be completely ignored, I lost all interest in the set.
BUT: for those who don’t really mind the changes to the OT, and who enjoy the PT, these blu-rays are right up their alley because the '19 versions are as good as all six films have looked on (officially released) HD.
