Not every cinema can play back the 6 channel mix; those that lack the 5 channels behind the screen usually opt for the 5.1 remix.

This new version is supposed to have the original mix on dts discs in 5.1. Six track audio with the five front screen channels can be properly placed in 5.1 or 7.1 codecs with no problem as you can properly mix for phantom imaging for commercial and home theaters that do not have five screen channels across the front. It seems some theaters are getting the original mix on their DTS disc and others are getting the warner remix 5.1 dts discs from previous showings.

5.1 =/= 6 channel 

The cinemas that do not have the 5 screen channels are mostly opting for the 5.1 remix, the cinemas that do have the 5 screen channels are mostly opting for the original 6 channel mix. That's all there is to it.

I am not saying this is accurate to 1968, but it is accurate to the timing I've seen on other 70mm prints from the last 15-20 years.

Thanks for your observations! I'm a little late on catching up to this, but I was reminded to check back on your experience after having found this latest "official" trailer . .
2001: A Space Odyssey – 4K Home Entertainment Trailer - YouTube
 . . which looks identical to the previous two "official" trailers over the past months.

Poor Stanley ...

Reading through this, I initially inferred that they gave it a teal cast deliberately. So... they left it untouched?

Went to the 72 minute mark on the film which shows the astronaut going thru a white corridor. On the Blu-ray it is a white color but on the 4K it has a slight beige color?

Sounds like that might be the HDR?

Quote:forum.blu-ray:
UHD looks fantastic. It’s the closest to the original print on home video yet, by far. I saw two different 70mm original prints, as well as the Nolan print. All three were practically identical. Comparing them to the UHD, UHD lacks a bit of the yellow warmth. That’s probably due to the 5500K-5800K projection xenon arc lamp. But it’s close. Setting the TV to the warmest setting pretty much nails the original look. Great release!

Is that bad?
