When I heard this had been filmed in 4K I figured BBC would push it pretty hard on blu ray but that isn't appearing to be the case.

If it was produced by the BBC or alterred by the BBC in any way, it's native framerate will be 25fps.

The group of people who designed the blu-ray spec forgot television exists outside of America and Japan (or that films might be shot at an unusual framerate), consequently 25fps cannot be achieved without the use of a 1080i encode (though it doesn't necessarily have to actually be interlaced)...
