That is a photosynthetic gorg and the colour is from the zooxanthellae. The white colour comes from either not enough light or too much and that's not healthy. I would keep the conditions the same for it as it looks in good health now.
As for the blueberry gorg. They are very very difficult to keep in captivity. I'm yet to read of anyone having any real success other than just keeping it alive for a few months. A couple of people have seen limited growth but this is in dedicated non photosynthetic tanks with near constant feeding. For the price of the frag you can give a go and if you do good luck.
Non lateral flow is confusing for a blueberry gorg or at least my interpretation of the term. Lateral flow is just a constant stream of flow in one direction and gorgs really need a kind of back and forth wave sway (which is why they have polyps on all sides instead of one). So it really needs a switching current that brings food to all the polyps.
