The standard BDs in the saga set use the 2019 masters while the sold separately standard BDs use the 2011 masters.
I’m in the same boat looking to buy the NEW color corrected blurays (I don’t have a 4K tv) Are you certain about what you said? Seems crazy if true. That Disney released TWO different versions of Bluray’s? Do you have proof of this somewhere? Thanks.
It’s discussed in this thread.
