Bill I think everyone has their own view as to what they want in an led fixture. My diy crees have a channel of royal blues that I use for moon lites after all the other led's shut down for the night, and although the whites may have a full spectrum I like a few reds, greens and warm whites to make the corals look as natural as possible to the viewer. As far as normal lighting goes I prefer 2 to 4 royal blues to each cool white to give the tank that deep water blue look and my corals open much better if I'm not providing a lot of white led's. The whites tend to bleach the corals much easier than the blues do if you run a fairly high intensity.
That sounds like a good mix.
As far as the Whites Bleaching more than the 450nm Royal Blue is an interesting observation.
