The pIqaD on the stairs of the Klingon Sarcophagus Ship has never been seen clearly on screen. A "behind the scenes" montage shown during this week's After Trek show provided a good look at most of it, including a perfectly readable closeup.

It's at 16:07-16:13 of Season 1, Episode 8 (released 11/12/17).
