Comment (by Balling):

 You understand that pirates on rarbg use ffmpeg? The metadata is correct
 for both the original bit perfect WEBDL or Blu-ray and downconverts. Dolby
 Vision content obviously could not be downconverted yet.
 So there should be a perfectly working script out there that uses that
 json ffprobe data, for example. Github is the place for it, or github
 gists. I will try to search through it /sigh
