I've done a small bit of testing with your custom picture control and my UniWB configuration.
My limited testing was with a lamp that has a translucent greenish tinted shade. With your custom picture control I found that if I exposed the lamp shade so that I just got rid of the black clipped indicator of your picture control, the green channel was still clipped in ACR.
I think this is because the combined RGB channels were not clipped once they're averaged out, as the R and B channels were under 255. But in fact the green channel was clipped.
I was alerted to this because I was using UniWB and the histogram I had up in the EVF alongside your custom picture control indicated that I was still clipping. Even though there was no black areas on the screen from the picture control.
I like your custom picture control workaround. However, I think it may need some tweaking to leave a little more leeway up at the highlight end. I'll have to think about it. As it stands, I think using UniWB and the histogram is more dependable.
