Where are those numbers from? They disagree with https://shotonwhat.com/skyfall-2012 . The IMAX release was done as a film print, which likely wasn’t made from the regular HD cut.
DP Roger Deakins has a forum on his site where he answers these sorts of questions. The Arri Alexa Studio was essentially developed for him, as he prefers an optical VF. It has an academy gate, and Deakins favours spherical lenses rather than anamorphic so we simply take the width of the sensor and crop down to 2.40:1 aspect ratio to get the quoted dimensions. Your link quotes the capture resolution, which will have some excess compared to the finished material.
This was put through the DI process and at a later stage IMAX DNR’d a blow-up to 15/70mm.
They showed Skyfall on 70ft IMAX screens, and that film was shot 2880 x 1200. Its not all about the pixel count.
