It seems to either literally be the 2011 mix or a tweaked version.
The biggest and most obvious issue to me is wildly inconsistent levels and feel to dialogue.
To pick one of many examples, take Luke’s line, “The Princess, she’s here?!”
In any mix from 77 to 97, it sounds just fine and fits in well with surrounding dialogue. But in 2004 and beyond it sticks out. It may sound a bit clearer or better on its own, but it is jarring in context of the scene.
