In dt some modules work on camera rgb, others on lab or prophotoRGB or whatever the output color profile returns. The final histogram and color picker collect the data after the last module (gamma) has been processed and display it in the display profile (and lab).
The color picker is returning inaccurate results and is being fixed in PR 2066 [1] (you are welcome to test it) Other than that, I'm not sure what your request is. We are talking about the final histogram, so this is the right place to collect the data. Do you want the data to be displayed in other format than the display profile?
