Hmh? Vulcan sky has already been blue, yellow, red and black (indeed all of them in ENT), plus brown and violet in TAS. The whole planet changes color, too. No doubt depends on the dust in the atmosphere.
We also got two round things in the sky, one of them very large, nicely matching the ST:TMP/TAS interpretation of what it means "not to have a moon".
Why should Vulcan only have one narrow type of architecture? We've seen plenty of styles: TAS, ENT, the 2009 movie, now this (which has echoes of all of the above). Thankfully, no caves, which is all we got in TNG and the TOS movies!
Interstellar mind melds were a thing in ENT already...
