Blu-ray info from  http://www.dvdbeaver.com/film5/blu-ray_reviews_72/2001_a_space_odyssey_4K_blu-ray.htm :
Firstly, this is not the 'Nolan Restoration' that some were contracting 'revisionist paranoia' about. But is has significant differences from the original Blu-ray.
The 2001: A Space Odyssey new image is, generally, darker and richer with the HDR whites brighter. Contrast looks beyond amazing. Detail - facial skin-pores instil realism in the image, depth is frequently prevalent and the visuals are even more hypnotic. This image is untouchable. Odyssey 4K UHD disc in this package has HDR (High Dynamic Range). HDR boosts a display's contrast ratio, which is the difference between the brightest and darkest colors your TV and can show greater dynamic range of luminosity. Increased contrast and color depth represent a dramatic leap forward from standard 4K. [...] Unfortunately, the vast majority of computer monitors cannot due justice to the 4K HDR image. [...]
Probably the most 'must-have' digital-film package in years despite the lack of new extras. This and Criterion's Ingmar Bergman's Cinema set will top our year-end poll. The 4K UHD presentation is 'sick' it's so good - I could have rewatched it over and over again on a loop. This should lead many to buying a new 4K system. Get this.... now.
