Here is a screenshot comparison between the Disney+ bonus feature, the iTunes bonus feature, and the fullscreen DVD release.
The Disney+ screenshot is simply hitting screenshot with the video playing in fullscreen in Firefox as I don’t have access to a DL source yet.
From what I see it looks like it might be slightly better than the iTunes rip but still worse than the DVD which is disappointing tho I am more than happy to be proven wrong in case I am just looking at it wrong or a rip would look better. I guess this means there is still a use case for my dvd/hybrid. Sadly I don’t have good news on that front. I have got no where near finished and at current am planning on just watching a cut with the iTunes footage edited into the blu-ray movie with the dvd commentary slapped on.
