Innovation or solution looking for problem? I think more of the latter...technology overshoot. My lights work fine. They are cheap, stupid, and when I flip the switch they go on/off. All requirements met.
That's all they do? If your requirements are binary, that may be enough.
Some people need lights that can be dimmed. Some people need a switch in more than one place, such as at either end of a long hallway or at the top and bottom of a flight of stairs. Some people need lights to come on automatically based on time of day, or when it gets dark, or when someone walks into a room. Some people need to remotely control lights. These aren't your needs, of course. You only need stupid lights.
There are solutions to each of these needs, but it doesn't mean those solutions can't be improved upon. And one improvement is bringing the control of various aspects of your home to a single interface, where you can manage any light, thermostat, door or window, motion detector, garage door, water heater, or coffee maker (to list a few) from a tablet or phone.
You'll still have switches, because who want's to mess with a tablet just to turn on the porch light if you're standing by the front door? The tablet is for checking the status of the porch light, and whether the door is locked, and who is knocking, when you're in bed---at your brother's house in another city, when the cheap, stupid light switch is not convenient at all.

I have never had the desire to change the color of any bulbs/lights in my house, other than to dim them. The blue light/melatonin thing thing is a bit odd since many of my bulbs are in fixtures where the light produced from the bulb never directly shines on me anyway. I don't get it.
The reflected light that reaches your eyes could still affect your mood, just as sunlight that doesn't shine directly on you does. These bulbs could be useful in internal rooms that don't get much natural light, as well as in winter months when the days are not as long.

What people want is for lights to turn on as soon as the Garage door opens so the lights will be on as soon as you get into the house. Plus timed lights when you are not home too.
What people want is not one single thing. Having house lights turn on as soon as you open the garage might be right for you, but then again, you might disturb people in the house who are sleeping or watching TV or making out in the living room and already have the lights set exactly where they want them.
