I'm going to jump in here and hopefully I won't look too foolish ....
however I think the top row looks more like what I'd expect. I wrestled with
this when I was doing the v3.7 scene file updates. I settled on
display_gamma = 2.5. You know the documentation example about dosen't really
talk about color. The example shows grey, black, & white probably best for
determining brightness and contrast. Componets of gamma correction right?

brightness looks to low to me. contrast compares with top row.
