Just as a note, there are (last time I looked) communities dedicated to rendering Star Trek ships (at least, there was last time I looked), and while some are new designs, many in that community are all about modeling or rendering ships from the shows. Just a thing that floats people's boats, some people don't want to create something new, but want to recreate a favorite thing of theirs. Some of my very first renders were Star Trek ships, getting on for 25 years ago now (though it was a "variation" and not aimed to be anything specific from the shows).
