"Vibes" are fair. I just put flashlights with two incandescent-like LEDs (Nichia 519A and Nichia B35A in 2700K) and I can see a slight difference in how they render colors even though the spectrophotometer says all the major metrics are within a couple points of each other.

What is the most logical explanation for the difference then?

Looking closely at the measurements, when the B35A has an advantage on individual CRI samples, it's usually a larger gap than when the 519A has an advantage. They're both in the 90s for R1-14, and it takes a keen eye to tell the difference.
