Location is only EU/US etc. Not country specific and UHD is not region coded so not sure how it would do that
I think they pick up the location of your player and play that regions default language.
Really appreciated your feedback, mate. Looking forward to order them! :D
All confirmed as English language and English subtitles - checked Chris Nolan boxset and Harry Potter set along with Covenant, in fact English is the default setting so only difference I suspect is the writing on the discs and box itself :D
Even better deal with the price drops. Picked up Nolan collection, Harry Potter collection and wonder woman, all 4k for £80. Bargain!
