One of the quotes we had included nothing but those lower voltage, smaller LEDs throughout. They told me that for the price, they could install about 4 of them per large LED. Also, even though they were low voltage, they would light the pool brighter than the bigger brother lights because there were more of them.
We did not end up using that company, nor did we get to see those lights in person. Our current PB only recently heard of them at all. But if you want extra light it sounded like (from the pitch I got) that those could be a good supplement for you. At $1100 / light (given you're doing it after gunnite) it does seem a little expensive. The areas which would be darkest wouldn't be as visible from the decking so it's really only a choice you can make on the matter.
