Hi what part about what I said are you disputing? If you're running the LED at 100% for 12 hours it is very very very likely most of that light is being wasted... Even in a high SPS tank this is likely way way too much light.
[It] is also proven that corals will grow different under different lighting. With more focus on the blue spectrum corals will actually change color. I'm talking about growth over months, not instant color change simply due to lighting.
I have kept corals in dozens of aquariums under different lighting and different flows and can speak first hand on the different in color and even thickness of skeletons between different systems...
The 5k bulb would grow quicker. Hopefully you have enough red spikes to actually achieve the benefits of that spectrum... I much much prefer the growth of corals under a 22K bulb, or more common 20K bulb. That 420nm of blues from actinic light will absolutely grow corals...

White light doesn't make a coral lose anything except immediate aesthetics. You can turn the blues on and instantly have a more colorful coral.
I have LEDs and I run my lighting for a total of 12 hours. I also have a 5000k lamp on some montipora that look rather washed out...but as soon as I turn the low K lamp off, bingo...my montis are colorful as the others again. I grow corals just as well as the next guy.
