Biography from Wikipedia via TMDB
Small role · Director: Blake Edwards
Kino Lorber 4K Blu-ray is from a new 4K master with some transfer issues, notably in the title sequence. The mono mix had errors and slight deletions introduced in the 2004 DVD remaster which were corrected on a 2006 DVD repressing. The Shout! Factory Blu-ray uses the 2006 corrected mono but those sections sound added in and in lower quality. The Kino Lorber 4K Blu-ray reverts to the defective 2004 mono. All the DVD, Blu-ray and 4K Blu-ray mono mixes sound poor when compared to the untouched uncut MGM LaserDisc mono PCM mix which is a direct perfect transfer and sounds excellent.

The 4K Blu-ray 5.0 is the original mix, but more muffled than LaserDisc and even the previous Blu-ray's gentle remix. The Atmos mix is revisionist.
The 50th Anniversary box set has some exclusive extras.
1991 LaserDisc is Dolby Stereo matrix encoded from the original six track master and this was later upgraded to a 5.1 Dolby Digital version prepared for the first DVD. The 5.1 version may have had some slight tweaking in the process. This was reused for the DVD CE boxset and then the 5.1 on Blu-ray seems like a slight upgrade of the DVD track. (The first pressing from the UCE boxset had audio defects rampant on the Blu-ray. These were corrected for standalone pressings.) All 5.1s sound roughly the same as the LaserDisc 2.0 in terms of the mix, but the LaserDisc PCM mastering seems like the only one that is direct without any major processing.

US Criterion 4K Blu-ray > International WB 4K Blu-ray see caps. While WB has better highlights, Criterion resolves grains better and is believed to have a more accurate color grading.
For Criterion 4K Blu-ray: The better resolution and the subtly adjusted grading paired with HDR makes for a more rounded, fine-tuned experience. The encoding is a leap forward from the Blu-ray as darker shots are no longer a macroblocking mess on the 4K.
