If it were a story that had yet to be released in any form, perhaps. But not in the case of, "Hey, this thing that you've already seen on BBC One is coming to home video." As laid out in T:OFF REL, the official release for Doctor Who televised stories is deemed to be the top or bottom of the hour after the BBC One premiere.

Now, if there are any additional special features on this release that were not a part of the non-UHD BD, it's possible pages about those might be considered spoilers. But would it be wrong to make a note on Twice Upon a Time (TV story) that a UHD BD is coming? Nah. In fact, I'd go ahead and put it in past tense — "was released on " — so as to avoid having to go back and change it to past tense after release.
