There was an article posted here earlier this year[1] that pointed out the flaws in modern LEDs, and just how hard it is to get one that matches the color you want. It's a pretty long read, but the author does a really good job of showing just how much trouble he has getting comfortable lighting that actually lasts a long time.
As I mentioned in some other comments, I settled on a lamp with a fully adjustable color and brightness. It’s lots of diodes, and the net effect is very nice.
In other words, I’m agreeing with your article that the fixed bulbs typically don’t hit the mark.
Are you sure that your "fully adjustable" bulb is giving you the spectrum you think it is? Syonyk's posted a few RGB bulb reviews recently, and they tend to have a lot more blue light than you'd think. And if you use the RGB functions, they tend to get REALLY spiky instead of having a smooth emissions curve.
Except people have already done these experiments, and it turns out trichromacy is quite common among humans.
If you actually dislike LED lighting then you should also notice issues with LED screens not just lightbulbs. Instead you like most people dislike bad LED lightbulbs which are common because most people are buying them without testing em. Which means most manufacturers don’t actually optimize for light quality.
If the spectrum of the LEDs match the sensitivities of the eyes, then everything is fine. But LEDs are narrow spectrum; they won't reproduce color the same way as a broad spectrum light source will.
As for LED screens, those are emissive and work great for simulating any color. However, they are not good light sources for lighting objects because they're narrow spectrum.
If the object you're lighting up is broad-band reflective (like paper with broadband black pigments), then everything is good. But as soon as you get narrow-band pigments, colors are going to be distorted.
You also run into the same issues with the images displayed via an LED screen.
There is no such thing as non distorted colors because even sunlight is also reflecting off objects in the environment. We are just used to seeing a decent approximation of what stuff probably looks like in full sunlight. It might be an old hack but changing a filaments temperature is only approximating what happens at different times of the day as the sun’s actual temperature and thus black body spectrum is constant what’s actually changing is the amount of atmosphere involved.
The truth is everyone doesn’t make the same corrections, individuals are simply fairly consistently with their approximation. https://en.wikipedia.org/wiki/The_dress
I worry we’ll find the high speed strobe almost all LEDs emit are harmful for humans or animals. We’re told they strobe too fast for us to perceive (sometimes true, sometimes not). But unperceptible doesn’t mean it’s not harmful.
A lot of people that use their iPhone’s slow motion video function indoors at night are surprised to see they are surrounded by a disco of blinking lights.
An incandescent has 10-15% brightness flicker at 120Hz. LEDs... vary. Some flicker a lot harder at 120Hz, some (mostly LED Christmas lights) are awful and flicker at 60Hz with a 50% duty cycle because they're a single diode rectifier.
Most LEDs flicker far faster, in the kHz range, which is theoretically beyond human impact, but we don't have many studies on it.
Incandescent flicker is also related to bulb wattage. A higher wattage bulb, with a thicker filament, will flicker less because it has more thermal inertia.
Filaments are slow to respond to alternating current. So they do wobble in brightness a bit, but they do not blink like an LED does, which fluctuates between 100% off and on.
A 240fps high speed is more than enough to observe a variety of LED flickering behaviors. Some flicker none (Bedtime Bulb is remarkable in the lack of flicker), some flicker at high enough frequency you can't really make out details, and others are just... gross.
