I don't agree, mostly. LED too high IMO is too high, too quickly from lesser light. Going from 400w MH to 6 LED units at 100% caused no issues for me.
Coral color is affected, but not sure the coral cares about that, simply adjusting pigments to compensate for spectrum. We choose to go for various colors, based on our preferences.
As for growth, typically I see more growth in SPS with whiter light, but simply due to the fact that whiter is generally more PAR.
