We currently have a List of BBC Blu-ray releases, which does exactly what it says on the tin, and is a continuation from List of BBC VHS releases and List of BBC DVD releases.

It has been announced recently that TV: Twice Upon a Time is going to be released on UHD Blu-ray in the US.

(Incidentally, the BBC is also releasing Sherlock Season 1 on UHD BD, suggesting that more back catalogue releases may be forthcoming in the future.)

Given that UHD Blu-ray is the same medium as regular Blu-ray (the discs are the same, just higher capacity to hold the extra resolution), my question is do we treat this as a new format (with a new list article), or as a subset of the existing Blu-ray format (similar to how 3D BD was treated for TV: The Day of the Doctor, Dark Water, and Death in Heaven)?

(Aside: "Ultra HD" is the correct terminology when discussing television. "4K" is strictly a cinema standard. While the terms are interchangeable colloquially, I would advise the wiki standardises to UHD, unless the BBC uses differently.)
