Hmm… but the actual display’s representation of 0 cannot be darker than the minimum brightness value it supports. If 1 really is 1x the minimum, then 0 and 1 have to be displayed identically. But then your scale isn’t even linear, nor does it have a true zero. How does that help?

edit: And aren’t output color spaces already highly nonlinear due to gamma correction?

0 is the lowest and x-1 is the highest for a ratio of 1:x. It’s 1 all the way to x; You just subtract one because computers start counting from 0

But in that case, skipping "even integer times brighter values" wouldn't exclude 0 - because 0 is 1x brighter, an odd integer.
