Hi, the US version of Blad Runner 2049 has 10000 nits metadata, the UK (and probably other EU version) have 4000 nits.
OPPO is not reporting the Primaries/White Point cordinates of the mastering monitor or MaxCLL / MaxFALL also.
US Blade Runner 2049 mastering monitor had REC.2020 Primaries while UK had DCI-P3 primaries (always REC.2020 is used as container and it's the colorspace you aim as target when you calibrate for HDR10/DV)
See a quick example of what differences some movies (and a lot of others will have when the list will be available) have between regions (while UHD don't have region code restriction)....interesting differences:
Looks like Blade Runner 2049 is the first movie mastered with 10000nits monitor using REC.2020 primaries.
Blade Runner 2049 is the second title which has REC.2020 primaries, there is another one from BBC US: Wild Africa/ Tiny Giants (but mastered using a 4000 nit monitor).
There 2 ways to calibrated a Studio Mastering Monitor, one is to calibrated it for DCI-P3 with REC.2020 D65 and at the end to put these data to a REC.2020 container and the other way is to calibrated the monitor to REC.2020 directly; to take advance a monitor which has higher coverage from DCI-P3.
