Perhaps I'm reading something wrong but here are the specs on the listing:
Audio | English (Dolby Atmos), English (Dolby Digital 5.1), German (Dolby Digital Plus 7.1), French (Dolby Digital 5.1), French (Dolby Digital Plus 7.1), Spanish (Dolby Digital Plus 7.1) |
Subtitles | English (for deaf or hard of hearing), German, French, Spanish |
Although the note says Achtung: die deutsche Tonspur ist nur auf der 4K Disc enthalten!
This translates to:
Attention: the German soundtrack is only included on the 4K disc!
I interpret that to mean that the German audio is only included on the 4K disc and
isn't on the Blu-ray disc.
That's what I get from translation through Chrome and Google.
