Yes that is true, although in film the cinematographer (or Director of Photography) plays a very important role in the look of a film. I think my words were a bit misinterpreted, I regard Stanley Kubrick as one of the best directors ever and 2001 and Barry Lyndon have my highest rating.
The role and work of John Alcott, who received an Academy Award for Barry Lyndon, must not be underestimated.
