Yeah, what we saw of the Enterprise in the pilot was just a re-purposed DIS-floor set with red accents instead of gold.
I like that they are taking this direction now, but it's certainly notable they are retro-fitting things, it would have been much better if they started out with this design approach.
I'll hold my judgement until we actually see more of the Enterprise - especially the bridge. Then we'll see wether they actually use updated TOS aesthetics, or DIS-aesthetics with a little skin on it.
One of my major beefs with the design language of DIS is it's very brutalistic approach - massive, bulky, intimidating sets. Whereas TOS had more of a sleek, stylish art-deco appereance. Both design languages have lots of sharp lines, edges and angles - but the TOS is by far the more individualistic approach, whereas brutalism always has... unfortunate implications.
One of the reasons why I even think Ryan Church's JJprise is a better update than the NX-01 inspired DISCOprise: He also ditched the art deco, but for a more organic style. He kept the sleekness and elegance of the design, which is IMO way more important than people realise, wheras everything on DIS looks so... block-y. Even the 60s Enterprise has more rounded edges (on the neck, pylons, deflector dish area) then the completely square & squat DISCOprise.
