I measured several sliced LH351D CCTs here including 2700K : LH351D slicing measurements : output, tint, tint shift, beam profile, intensity.
It doesn’t go that low in my experience, but yes it’s a good option for a very warm 3535 90CRI LED.
Dedomed 2700K 219F-V1 or even beter 519A (9080 and lower thermal resistance) would also be an option, they should be easy to dedome thanks to their silicone dome on top of glass encapsulated phosphor.
