It took me a good 30 seconds to actually realize that this was a picture of a moving (I imagine) enterprise. Before that I kept seeing a weird shower head.
I think the goal of the Star Trek marketing is to keep the core trekkie audience interested while also significantly broadening the series appeal. A big white mess seems unlikely to achieve either of these goals.
And even after you figure out what the image is, it’s still not very interesting. The enterprise going fast. A different depiction from those we have seen before, but one that doesn’t actually add much.
Maybe the idea is that by doing something that can’t be immediately understood they will get people’s attention, and that when these same people figure it out they will remember the Enterprise clearly. But this sort of strategy seems as likely to irritate people as it is to engage them.
