It is basically impossible to do on the bulb level or it would have been done a long time ago. LED OCD is the solution for insert lights. Sticking to real bulbs is the solution for GI lighting.

i just recently installed LED OCD on my STTNG and it is .... amazing. night and day. the sharpness of LEDs, any arbitrary brightness i desire, and whatever fade level i want -- all configurable on a per-bulb basis. also no strobing or ghosting. great product.

I will never use LEDs specifically because they look harsh and have a strobe like appearance rather than a warm glow.

This is of course in the basis: people designed a lampmatrix which is controlled the way a bulb works: a slow glowing thing which heats up by current and produces light.
Then someone puts in a led, which works in a different way. Much faster, and with a minimum voltage. That works more or less, but it has some problems (ghosting / flickering). The problems are caused by the way of controlling (which is designed for a bulb, but must control a LED). So the way of controlling is the issue, not the leds themselves.

I don't know LED OCD, but what I read on their site it is a complete new way of controlling the leds, based on information as the game tries to control the matrix. If they control it in a good way it probably works perfectly. They are controlling leds the way leds should be controlled.

.

Now the next mod is doing the same for the GI. 3 or 5 triacs now control the GI, so the signal from the triacs can be evaluated by a microprocessor and then the MOSFETs can be controlled.

That would be a quite simple thing to do: read the AC waveform on the lightbulb as analog input on an Arduino (or so), then control a DAC placing voltage on the gate of the MOSFETs by the logic. Or something doing with a pulsed DC which works for bulbs as well as leds.

LED OCD GI perhaps?
