No, 4K mastering has been going on for a while now. Plenty blu-rays already have 4k masters. Some have even been scanned at 8k from their 70mm source, while remasters are generally scanned at 4K from 35mm. There is only a small gap of the early naughties that is plagued with a 2K production chain. You will never see LOTR in proper 4K as that was all filmed and produced in 2K. However Ben Hur (1959) will look excellent in 4K.
Pretty much all movies are now filmed in 5k and mastered in 4K, 2K digital intermediates are a thing of the past.

It is early days and the list is still quite small.

I would not say 2k digital intermediates are a thing of the past:

"Mastered in 4k" does not mean true 4k resolution. It simply means a 4K scan of the original camera negative. The output of these "mastered in 4K' discs is still 1080P. The 4k scan is then down-converted to 1080P, compressed and authored(amongst other things). These disks do look better than standard 1080P disks, but it is no where near true 4K.

Some UHD blu rays are finished on 4k digital intermediates but a strange amount of very recent films where finished on 2k...

Wow, thanks for showing that. I always check blu-ray.com before buying anyway, but I didn't think the industry would be so stupid. Ofcourse, I should have known better with the early single layer mpeg2 blu-ray discs.

Here's the culprit, the movies were made in 2K

X-Men days of future past:
http://www.imdb.com/title/tt1877832/technical?ref_=tt_dt_spec
ARRIRAW (2.8K) (also dual-strip 3-D) (source format)
Digital Intermediate (2K) (master format)

Max Max Fury road:
http://www.imdb.com/title/tt1392190/technical?ref_=tt_dt_spec
ARRIRAW (2.8K) (source format)
Digital Intermediate (2K) (master format)

I stand corrected, 2K is still a thing :( I guess 4K cinema is a lot slower in uptake than I thought.
Even the Martian still has a 2K digital intermediate.

The Revenant should be in actual 4K
ARRIRAW (3.4K) (6.5K) (source format)
Digital Intermediate (4K) (master format)
