The Paramount 4K "restoration" is a desecration. It has completely revisionist color timing, harsh HDR, treatment of stock footage, bad encoding, selective DNR and grain management so bad that the entire screen frequently freezes up with only characters moving around in grain soup. It is so bad that the film's restorer Robert Harris publicly washed his hands of it saying essentially the 2007 restoration (with Willis and Coppola supervising) is how the film was intended and made. This is Paramount's modern version done their way. The new 1080p SDR Blu-rays in print are the crap 4K desecration master with the same problems still there just harder to spot and with crap encodes. Part II overall fares better than the first film but it has all the same problems. Randomly some shots are the worst in the trilogy looks mushy and manipulated to death.
The mono option is an unnecessarily processed version of the lossy mono from the 2008 Blu-ray. The 2008 Blu-ray of the 2007 Coppola Restoration while an imperfect outdated disc is LIGHT YEARS better than this 4K desecration. The only truly major issue is that it is very slightly redder than the 2007 finished master as seen on DCPs. The lossy mono on the 2008 Blu-ray is the best version of the original mix known to exist as it is better than the late 80's mastering for VHS and LaserDisc.

The original 1977 censored cut has never been officially released on home video. The 1981 cut and the 1990 EU cut are available on VHS. The 1992 Trilogy cut was released on LaserDisc and VHS. The 2012 and 2016 HD versions were broadcast on AMC and streaming HBO respectively but neither are available on either platform anymore currently. The Chinese 1080p blu-ray on the high seas is probably the most accessible and affordable way to watch it, (albeit with terrible compression) and appears to be a Webrip of the 2012 AMC HD tv broadcast. It’s on two BD-25 discs with lossy Dolby Digital 5.1 audio and with subtitles for Sicilian dialogue.

In the Lionsgate US/UK 6-disc set, there are 4 discs of the main feature. For whatever reason, the 4K discs lack the *original track. The Germany 4K Blu-ray release is different on this matter.

1. UBD: Final Cut: Atmos, DD2.0

2. UBD: Redux/Theatrical: Atmos

3. BD: Final Cut: Atmos, DD2.0

4. BD: Redux/Theatrical: Dtru5.1 (Redux mix?), DD5.1 (?), DD5.1 (Theatrical only), DD2.0 (downmix??)

   1. As a result the Theatrical Cut has 4 tracks, The Redux has 3. Differences are unclear.

5. BD: Hearts of Darkness

6. BD: Special Features

2011 Lionsgate Blu-ray slightly better
