Knowing how the WB, expressed as a standard light temperature in K, is implemented internally by different vendors is certainly an interesting topic by itself. But my question and concern is really about traceability and acquiring experience.
I take thousands and thousands of pictures, and even thought I shoot in raw, and i know i can later do some WB adjustment, i try to make the best settings when I take the pictures. Old reflexes are hard to discard. WB expressed K is my reference and slowly, over the years, I gained an ability to judge the color of the light, in K, and set the camera accordingly. Now, I understand (and see) that the final result can be very different depending on the camera profile, but also on the vendor of the raw conversion application (LR, NX, C1, etc.) i use. Nevertheless, the world have to make sense and be stable so that we can build knowledge and when I set the camera to 7000K, I want to be able to know one year after, or one week after, what was the K I had set in the camera (the light might be the same, or slightly different). It seems that contrary to other vendors, Adobe Light Room designer has chosen not to display my original WB intent (in K), but the internal numbers they use to achieve that WB. Suddenly, 7650K -NIKON is the same as 7400K - in LightRoom. Its a programmer's playground, not a photographer. I take pictures and don't run around with conversion algorithm (even though once in a while its fun to talk about it).
So is there a way... a hidden button in a nth level, a secret password, where LR can remind me what were those 4 digits i used for K when I took the shot? Everybody else does it. It would be very useful for me.
