LED MR16 GU10 2700K lightbulbs compatible with Diva DVCL-153P dimmer?

I'm having a hard time finding replacement LED MR16 (type) GU10 (base) 2700K (color temp) 90+ CRI lightbulbs compatible with the Diva DVCL-153P dimmer. I'm in California so it needs to comply with the title 20 regulations as well.
The only matching 2700K bulb listed in the Lutron LED compatibility tool was dinged a star for flickering, has unknown CRI, and doesn't conform to title 20 (which is probably why it shows as unavailable for purchase online at Lowes). I also checked some of the other bulb finders and was unable to find any matching this criteria.
This is for existing track lighting and I prefer the 2700K color temperature to the (more widely available in this style) 3000K.
Does anybody have any leads on a matching bulb?

It's not clear why you specify title 20 bulbs, whether you need some kind of traceability for institutional use, for example, or you just want to be a good citizen. If it's the latter, any bulb you're likely to buy at any CA retail store will be compliant. If for no other reason that title 20 compliant bulbs fall under extremely commonly desired kind of general purpose bulbs.
FWIW, GU10 bulbs may be exempt. And yes, title 20 is exactly the kind of regulation that people rightfully roll their eyes at CA for.
Your other demands may be far more tricky. I know nothing about the Diva DVCL-153P dimmer, but dimmable LED bulbs are always convoluted weird little contraptions that may or may not really satisfy your dimming needs. Dimmable LEDs really need to be designed from the ground up as a system rather than a backward compatible bulb that was intended for incandescent bulbs. Since almost nobody is willing or able to do so, bulb manufacturers employ driver circuits that sort-of, kind-of work with dimmers, maybe even to your satisfaction. In my experience, some are better than others, some don't dim very linearly at all, some kind of flicker, or are inconsistent. Color is pretty commonly listed these days, CRI less often, and other characteristics like flickering, good luck. May be subject to individual manufacturing variability. For example, I have a kitchen fixture that uses 4 GU10 dimmable bulbs, all 4 bought at Ikea at the same time, but one works inconsistently at the dim setting. I think the dimmer might be an old school capacitive dropper, so I'm kind of surprised they work at all, but these are exactly the sort of issues that come up with LEDs.

When I have questions like this I call Energy Avenue in Las Vegas. They're really knowledgeable and have a huge stock of bulbs/ dimmers/etc.

Response by poster: Thanks for the input everyone. I ended up finding these bulbs which match my criteria and specifically list the Diva DVCL-153P dimmer as compatible. Fingers crossed!
