AnsonPike's expression at 0:55 gave me the sense that something is a bit "off" with the fabric of reality, or something. Like in a Guinan/Yesterday's Enterprise kind of way.they know what the Cage era looks like. TNG did their love letter to the TOS era, DS9 did, and this was the CBS era's version.
CBS is just going for their own look. They have never shown any interest in 100% recreating past looks, and that's fine. In some cases I think it works well (Discoprise), other times it has fallen flat Fuller's Lizard Doublepeener Klingons, for instance.
