Could be SONY is using 4K Studios to remaster their
Top Line films in 4K+HDR Format. After all NTEK
Pr'd clear back in July 2015 they were gearing up
for the HDR format.

If true that would be HUGE bucks for 4K Studios
because the HDR format will command the highest
profit margins since its as top of the line premium
as you can get in Content Quality. Only the Best
Films are going to get mastered in 4K+HDR format.

Maybe that's why we havn't got a big upload of
movies on UF lately because they've been working
on something like this....hmmmm....
