Pretty laughable to be complaining about quality and claiming it’s an upscale if you’re solely comparing it to a YT upload; if there’s a trailer on D+ I’m unaware of, that’s a different story. Y’all do have more technical know-how than I do, but that seems like a stretch.
That being said, check out the shot of Han at 2:02–wonder where that source came from. I don’t think the GOUT has the damage evidenced in those frames. It might not be a new HD scan, but it’s definitely different footage than what we’re used to from Disney.
