I'm sorry but you're really not getting the point. The look of a futuristic, made up device tells you absolutely nothing about it's futuristic, made up functioning. Not only that, but common sense and experience tells us two similar looking devices may be, in fact, very much different from each other and two devices that look totally dissimilar may be, on the inside, exactly the same.they can't be the same.
Look @ NX-01 TOS style Dish.
Look at all consititon class ships TOS Style Dish.
given the Kelvin was active in 2233 it predates Durotronics even, and at launch the Consitition class in the real timeline was the most advanced ship in the fleet, and the USS Consititon wasn't active till the 2240's so that makes the Kelvin bases around older technology, that means the dish wouldn't be TMP Style, it should look like the dish aboard the NCC-1701 from the real timeline. I'm guessing you havnt taken any time to actully learn about the tech ect behind star trek.
Not to mention explain the L'Cars style interface or the bridge design, if this is the break in prime it shouldnt look that way at all. I have a thousand gripes just about this one ship
So what one has a blue color and no spire and the other does not. They're both still the same. It's not as if, for example, impulse engines have ever looked the same or evolved in the Star Trek universe in a gradual, linear fashion.
