I am very impressed by the introduction of this advanced color tool. I watched several presentations, so far, and kudo to Adobe Photohop's engineers! I really like Julianne Kots coverage on YouTube, btw.
Only one "problem" and to me it is a big one. Why on earth did the team chose the term "Luminance"? Over the more fitting "Lumnosity" term, as in Hue, Saturation and Luminosity? As far as can see, Camera RAW has no influence on the "actual Luminance" in Candela/meter square being emitted by the monitor? Does it?
Luminance is a long standardized CIE term. It has a physical definition and is being used wrongly here. If you have any doubt, please refer to CIE Publication No 18.2 "The basis of physical photometry", Section 4.2 where it is defined along with Radiance. It should be changed over to "Luminosity" which is what's actually going on while editing color using the Point Tool in Camera RAW.
Please, Mr Adobe. Do everyone a service and change it in the next dot release.
