I think you're reaching a bit. Observe the symbol in full before you ascribe meaning to any parts of it. My observations: The symbol is comprised of a number of geometric shapes. The Roman numeral for 9 is above it. If you view it from the side, you can see a violet glow shining out. If you rotate the camera up close, or watch for a minute, you can see what appears to be a shimmering star field. It's the same view, no matter how you rotate the camera. Basically, it appears to be cross dimensional graffiti. What it means, I have no clue. It certainly could be related to the Nine. I'm curious to see if the same symbol, or a similar one, can be found anywhere else, especially on the dreadnought. That's currently the only location that could have a view of deep space like that. Fwiw, the north most planter also has some flowers in it, though they're not nearly as colorful.
