About the only reason I could think of to buy smart lightbulbs would be to suddenly turn all the lights in the house red, and yell "torpedoes in the water, brace for impact!" and that doesn't seem like a strong enough argument. I'd probably only do this 2-3 times a month anyway.
There do exist products made for for a variety of Youtube/video/streaming needs, including lighting, and they are niche.
You might think "but there are many many Youtubers/streamers" but in comparison with the overall market for such lamps, they're insignificant in number.
Hue and co (from Amazon, IKEA, etc) are mass market products.
