My Histogram in LRc is showing only the RGB colors, how can I get also the CMY colors displayed in my histogram, The CMY colors as you know results from the overlap of colors from RGB. How can I get RGB and CMY displayed in my histogram? Thank you in advance

There's no way to display CMYK. The histogram only shows RGB.

Almost all of the LRC Histogram images I have seen in YouTube videos and LRC books do show the yellow, cyan, and magenta colors where RGB intersect.  Could it be only a Mac capability and not available on PCs?   I have a new Dell XPS Desktop 8960 Intel Core i9-14900K, 64 GB Ram, and NVidia GeForce RTX 4070 with 16 GB, and BenQ SW272Q  -- this configuration is VERY strong for my LRC 14.1.1.  But STILL not intersecting colors yellow, cyan, and magenta.   Very frustrating!!!

UPDATE:  I just disovered from an Apr 2024 post by John Ellis (https://community.adobe.com/t5/lightroom-classic-discussions/question-about-the-histogram/td-p/14578013), that as of LRC 13, the intersecting RGBs are no longer displayed as yellow, cyan, and magenta.   The Adobe documentation now notes that "A histogram uses semi-transparency and lines to indicate where the different channels overlap."   But in the following paragraph, Adobe still claims that the RGB intersection are displayed with yellow, cyan and magenta  --  which is now incorrect.  Come on Adobe, update your Lightroom documentation!
