I'm not. In my head, the Enterprise bridge (and exterior) has always looked the way it did/does in Discovery and SNW. The reason it looked the way it did in the 60s is because we didn't have TVs that were high definition enough to see it properly![]()
I think that was always the intent. It was implicitly the idea behind TMP as well. Sure, the new ship is a refit, but it doesn't make sense to assume that literally every piece of technology was drastically redesigned simultaneously. Upgrades are usually more gradual than that. I think the idea was that if we'd seen the original ship with better "resolution," we would've seen that it had hull plating, reaction control thrusters, docking ports, etc. like the TMP ship did.
The reason "Relics" and "Trials and Tribble-ations" recreated the TOS sets exactly was because they had to match stock footage from TOS. ("Relics" used a stock shot for the wide view of the bridge, since they only had the budget to rebuild the turbolift alcove and one console, and to rent fan replicas of the command chair and helm station.) And the sets in "In a Mirror, Darkly" were expansions of the sets used in the previous productions. If they hadn't been operating under those limits and had been able to start from scratch, they might've updated the sets too, though perhaps not to the same degree that DSC & SNW have.
