Now that I'm a year older, strange things come to my mind - Grampa Simpson may have better ideas, but I'm digressing...
OK, here you are my idea: even if 4K has green pushed too high, it has some quality, while Mondo is better but not perfect... what if... I take the best of both worlds? I took the film screenshot, regraded to both 4K and Mondo - the latter twice, once "as is", and once taking the levels from PC to TV - then I merged the regraded images and here you are the results:
