OK, let's stop for a sec - Arris' ALEXA records files that are nothing short of
amazing quality RAW footage, period.
First, 4K studio transfers are much better quality than ****** publisher re-scans.
Second that ALEXA has a
DR of 14 stops, even if it shoots at 2K and Skyfall was pretty awesome quality, you must admit.
Third,
most Digital Cinema theaters are still running with 2K projectors.
Lastly, even IMAX is (dual-projected) 2K, remember.
DP of Skyfall Deakins about shooting with ALEXA (he had the first units, 3 different models):

"I did side-by-side testing and found that there was so much more latitude in the file from the ALEXA than in a 4K scan of a film negative. I was also drawn to the subtle fall-off to highlights and the enormous amount of detail in the shadows. It was the first digital camera I had seen where I thought the technology had crossed the knife edge and taken us into a new world."
How the IMAX version has larger AR due to ALEXA's taller RAW format:
