Zavvi lists the following for the language specifications:
Disc 1: English DTS Headphone:X & English DTS:X (Theatrical and Extended Versions), Czech, French, Polish (Voiceover) DTS Surround 5.1
Disc 2: English DTS-HD Master Audio 5.1, French, Italian, German, Spanish, Japanese DTS Surround 5.1

I assume disc 1 means 4K and disc 2 regular BD, am I correct?
