Plus the immediate recognition of the landing part in ep. 15 as Human, not Augment Klingon. And that can't be explained as 'they smelled human' or something because Tyler is literally a damn Klingon. I would say human looking Klingons, Tyler style cosmetics aside, are not part of Discovery's world. This is just another version of the Klingon design.It makes zero sense and a human shot would totally change the Voq/ash story.
ETA: The 'twist' at the end of the Trouble with Tribbles implies there was always a visible distinction between humans and Klingons which is perhaps not on display through 60s makeup, or Arne's 'pretending to be Human' is literally just changing his shirt and combing his hair. If it is that difficult to visually distinguish the two it raises the question of why a brief tricorder scan was not a prerequisite for officials, especially near disputed space.
