> How can I get camera RAW to display color readouts in Lab instead of RGB values ?
mouse over histogram + right button click

you need to use dcamprof to create dcp profile(s) in a proper manner, as it is a much more powerful tool vs DNG PE or X-Rite OEM software, I think I emailed you the links when I saw your question in colorsync mailing list
PS: as for Ben Goren there - he demonstrated a great deal of ignorance about tools = "To the best of my knowledge, not a single vendor sells _any_ product for building DNG profiles with anything other than a 24-patch ColorChecker"... who cares about commercial products when you have a free one :-) ...
Ben is going again in ColorSync = "you're still stuck with the bizarre illuminant nonsense that does this automatically-estimated blending between A and D50 with no meaningful user control nor input."... does it happen to him that you can create a single illuminant profile for your specific light and put illuminant code as OTHER in dcp profile ? at least he suddenly remembered that dcamprof exists
Thank you for your reply to my question and for very helpful answers. I really appreciate you taking the time to help me with this.
I tried what you recommended but it doesn't seem to work. Again I am running Photoshop CS6 and ACR 9.1.1. Could it be a version issue ? Could it be that the right click and the Lab readouts only work in the newer Photoshop CC and its ACR newer version ?
I just now saw your answer and your post. I am going to read it carefully and try to follow your instructions.

it seems so... so one more reason to bite the poison pill !
Yeah, Lab readouts in ACR is a new feature only visible in CC-hosted ACRs.
Finally!!!! Thank you. Thank you. Thank you for the hint of how to get the histogram and color sampler tool in ACR to give Lab color info. Mama mia, my dream has come true! To have the L, the a, and the b channel info in ACR is fantastic! I use Lab color info. for nearly all my color work no matter what color profile I apply to my image (Prophoto RGB, for example). The L channel (luminosity) has a big influence on color and I like to see what it is on the Lab scale in order to comprehend it; and see it together with the a and b color channels. My monitor is color calibrated by me every couple of weeks yet when it comes to color work, I always work closely with and trust the Lab color info readouts; and tweaking color using Lab info. is easily comprehensible and easy to keep track of; and of course, the print always has the final word....
