Measured after building them, on four of the library's 6D DNGs: Adobe
Standard's tables lower mean saturation by 3-9 % at defaults, and the
look at 200 % lowers it further. The 6D's look table scales saturation
by 0.925 in its darkest value rows; it was tuned to sit under Camera
Raw's default RGB tone curve, which DarkRoom does not apply, and the
dark-tone desaturation is what is left without it. On _MG_9080 the
Lightroom preview measures 0.49, the matrix alone 0.38, the profile
0.35.
So the spec's "that gap is most of why the same file looks flatter"
was wrong: the gap is tone. The tables stay — they put each hue where
Adobe put it — and the spec, D20 and the Vivid file now say so.
"Stronger camera look" is removed: a stronger Adobe Standard look is a
less saturated picture, the opposite of its name. The Vivid presets,
measured at 0.40-0.46 on the same frame, are what answers "more
colourful" today.
