Of course, in the strictest canon context, there is no "The Cage", and Pike's adventure is a dream sequence in the middle of "The Menagerie"...
What to take and what to leave in a dream sequence is an iffy question, though. In "Flashback", say, it's explicit that the dreams are false, part of the disease wrecking Tuvok's brain, and contain (indeed, depend on) deaths that never took place. The ships still supposedly look the same. Do the uniforms, or is it a mere fantasy of Tuvok's that Janice Rand would be his boss rather than a co-irker?
The uniforms of "The Cage" appear to be the one thing DSC intends to preserve, though. The upcoming tribble short has a crew wearing the all-Lieutenant-braid style, with the subdued grayish-navy-blues and all!
