"Tint" and "CRI" are not the same thing.
Tint - refers to whether you're above or below the black body line. Above gives greenish tint. Below gives rosy tint (which most people prefer).
Color Temp - refers to the LED's left-right position on the black body line. Left is warm, right is cool.
CRI - refers to how accurately colors appear at the given tint and color temperature. High CRI gives much more accurate color rendition and tends to look better.
It is possible to have rosy low-CRI and greenish high-CRI.
The 2020 Jetbeam RRT-01 uses a 70-CRI 4000K Nichia 219C emitter. It has a pleasant tint. Yellow, perhaps slightly rosy. But due to its low-CRI nature color rendition looks pretty poor with it. Note however, the the difference between low and high CRI can be subtle. If all you have is low-CRI, your eyes adjust and it probably looks fine. But shine its beam next to a similar light with the same emitter in high-CRI and the difference is immediately apparent.
I'm no stranger to high cri and tints, but no harm posting what you did. If the rrt01 2020 Nichia isn't high cri than half a dozen distributors and double that in reviewers on YouTube have it mislabeled as such. In this day and age I just don't see Nichia selling a low cri neutral white to a manufacturer. Is it possible yes, but likelihood no. I'd be interested to see proof
