2011 Blu-ray/2021 4K Blu-ray

The 2011 Lionsgate Blu-ray is incredibly poor for every Original Trilogy film; older processed older DVD-era masters with heavy use of DNR, sharpening and edge enhancement with a really dull color grade. The 4K Blu-ray is miles better. The DTS-HD 5.1 across all three films appears to be the same on both the Blu-ray and 4K Blu-ray, and they appear to be the untouched theatrical 5.1 mixes. 

The Uncut version has more violence: https://www.movie-censorship.com/report.php?ID=256325

France M6 Video - Geoff D review.

Lionsgate 4K Blu-ray disappointing - Avoid. Terrible release. Another Kino-grade encode with a huge DV layer. The Lionsgate Limited Steelbook has a different disc with exclusive bonus discs and apparently another poor encode but they also messed up the DV metadata and made that disc unwatchable with DV enabled.
