Thanks, fiddling around with “Color Rendering” help!
As pointed out by @Egregius days ago, this color rendering trick really help.
Here are photos for illustration (I accidentally overexposed this shot because I was photographing a bird on bright background, then I saw this common chiffchaff). I applied the “no correction preset” then changed only the color rendering.
Default rendering: chest overexposed
Neutral tonality v2
Realistic tonality: best dynamic range!
Sorry, I did not reazd the whole thread…arrived after battle.
Nevertheless, now you have the explanation.
