Beware of the hype around "high CRI". It's more of a global snapshot of a light's various colour rendering abilities. I've seen some "high CRI" bulbs with shockingly bad spikes in certain colours. What you really want to pay attention to is the individual R1-R14 values and make sure there's no dips. For example, if you're looking to replace your household tungsten lightbulbs then it's really important to pay attention to the R9 value that your LED ilght has (1), as it refers to the red value being emitted by the bulb and is what affects skin-tones. And, yes, CRI is completely independent of temperature. You can have a daylight or tungsten LED bulb with completely varying CRI values.
