This is my best guess of what PS is doing.
Code: Select all
convert infile.jpg ^
( -clone 0 -colorspace Rec601Luma +level-colors black,red -colorspace HCLp -separate ) ^
( -clone 0 -colorspace HCLp -separate ) ^
-delete 0,3,4,5 -combine -set colorspace HCLp -colorspace sRGB ^

If you like, I would be happy to make a go at reproducing this, but I'm at a disadvantage not having PS. I would need some PS outputs from you.

Yes, that matches visually better. The PS dark areas are slightly darker than from IM.
This was what I tried to do in my last set of examples when I tried to remove the linear RGB conversions, but I overlooked one.
infile="sunsets-lightroom-split-toning_srgb.jpg"
inname=`convert $infile -format "%t" info:`
convert $infile \
\( -clone 0 -colorspace Rec601Luma +level-colors black,red -colorspace
HCLp -separate \) \
\( -clone 0 -colorspace
HCLp -separate \) \
-delete 0,3,4,5 -combine -set colorspace
HCLp -colorspace sRGB \
