Well, the corals don't care about colors like that...you'll never bring a new coral home and have to turn up the red, for example.
Sunise/sunset, lightning storms, moon lights, tweaking exotic colored LEDs....all for you and me, the owners. Corals don't give a whiz.
To an extent you can incorporate some of those ideas in a gu10-based fixture, but I don't.
(I do have a Maxspect Razor on my other tank so I could check out the sunrise/sunset effect....just wish I was around more to see it. Definitely not worth paying extra for IMO.)
Maybe someday when we can do an actual sun and moon simulation (they aren't stationary) coupled with a tide simulation....then it'll matter to them. Until then I'll go out on a limb and say that none of the successful tanks you can see in a look around here are successful due to any of the features mentioned. (Some folks may be doing this already, but not without some specialized gear and programming....it's not impossible.)
Consider also that a lot of the adjustments on commercial fixtures are there only to account for the fact that they don't know what tank they'll be on or even how they will be mounted. A DIY doesn't suffer from such uncertainty since you are there during the design phase.
