I take a hobby interest in lighting as design and art, and probably have more lamps than I should have. My personal view is that it's not really an area that is being ignored. There are a lot of companies in this space developing new lighting.
One thing that concerns me about investing a lot into current LED lighting is that it seems like the tech is still evolving. At least that is my impression. I don't really like tech that gives the illusion that it will last a long time but ends up useless after 2 years. I see some really interesting lighting designs but it's all built into the lamp---does this mean lamps, usually a durable good, are just disposable units now? LEDs are supposed to fade over time---what do you do with a perfectly good standard bulb that's producing 25% less light? It still takes up an entire lamp socket. If it's a whole unit, that's a footprint in your home occupying space producing significantly less output.
Some LED bulbs I bought a few years ago are basically outdated in terms of light quality. I think my favorite bulb that I've tried is by Cree. People don't often believe that the difference is noticeable but when I swap out bulbs of various types they can notice how much better a room feels or the colors pop more.
You also can't buy several 'bright home' sunlight level lights cheaply just to see what looks better, so I wonder if this might be an area that keeps brick and mortar lighting stores or sections relevant.
Then there's also the environmental concern of eliminating any of the gains of reduced power consumption by buying more powerful LED bulbs that consume just as much electricity.
Another aside: If you're bored, playing around with lighting in Unreal Engine 5 is pretty fun. UE5 seems very impressive.
