Bitrate Graph

Flicked through the film, and compared to the German UHD it more or less seems identical from what I've seen. No obvious discrepancies in regards to colours or anything either. The only real difference between the two seems to be in the Atmos track, with the mediainfo reporting 15 dynamic objects vs 11 on the German UHD. No idea how much difference that realistically makes as I don't have anything that supports Atmos playback.

Also worth noting that the UHD retains all the extras from the BD, encoded at double the bitrate (20mbps vs 10mbps on the BD) however both are x264 CBR encoded. In fact everything on the disc, including the menu, but excluding the main movie file, is once again SDR 1080p x264 encoded like the BD was. The subs are also the same as the BD (dullish white rather than grey) albeit positioned slightly higher, although the previously broken subtitle is now rather humorously half way up the screen, rather than off the bottom of it.
