The Senitype cells are printed from a single, selected frame of the actual film (70mm in the case of 2001:ASO) – so they are all identical. But as this was a special item, I would think they’d put in the extra effort needed to get it right.

Senitype® - About Us webpage:
The creation of Senitype® begins with the careful selection of a single frame of film that is digitally scanned and expertly reproduced onto paper using intricate state-of-the-art imaging and printing techniques. The film footage is an actual 35-millimeter/70 millimeter or other size(s) film frame reproduced from the original motion picture negative by master film technicians.

These were originally included in the collector’s edition DVD sets released in 2001 (see it in that YouTube video, previous post).

Also, what’s off-topic cool is that they’ve made LOTS for other movies we all know and love, here, at OT!
