After pushing out the last post, I've tried to educate myself on gamma vs linear, eg https://www.imatest.com/2021/07/tonal-response-gamma/

I've convinced myself than the viewport based CHDK (and Canon?) histogram are gamma encoded at 2.2.

Thus the top 1/3 stops look like this: 255-229, 228-206, 205-185.

This follows from: 256*2^(-(n-1)*(1/2.2))

Another test I thought some may be interested in, especially if you wish to do some close up photography.
