Edited mostly to fit the subtitles in the black bar below a 16:9 letterboxed picture. Probably looks stupid on ultrawide monitors.
The 1080p and 4K Blu-rays that I have differ by exactly one second. Obviously there are other BD releases out there, so your mileage may vary.
For HDR playback on Windows I’d recommend madVR with MPC-HC or MPC-BE.
