This part puzzles me. Why do studios film in 4K, only to finish on a 2k/1080P digital intermediate, then to upscale to 4k for the UHD release? Would it not be better to finish on a 4k intermediate and then downscale to 1080P for regular blu ray?

Because a 1080 image on a cinema screen would be fucking horrifying?

Erm, 4K projectors have only recently been introduced in cinemas, Most still have 2K projectors. Frigging digital IMAX was (and still is in many places) displayed on dual 2K projectors. 2048x1080 is the 2K cinema format.
