8 months ago A draft I made:
...
# change wallpaper image for given desktop on all displays
/usr/bin/xfconf-query -l -c xfce4-desktop | grep "/backdrop/screen0/monitor.*/workspace${currWorkspaceID}/last-image" |
while read -r line; do
# check whether both dark mode and wallpaper dim are ON;
# see https://github.com/doomemacs/doomemacs/issues/6027#issuecomment-1019373126
if (echo $(gsettings get io.elementary.desktop.background dim-wallpaper-in-dark-style) | grep -q "true") &&
(dbus-send --session --dest=org.freedesktop.portal.Desktop --type=method_call \
--print-reply /org/freedesktop/portal/desktop org.freedesktop.portal.Settings.Read \
string:org.freedesktop.appearance string:color-scheme);
then
input_image="$1"
convert $input_image \
-fill "rgba(0,0,0,0.45)" \ # see https://github.com/elementary/gala/pull/1651
-draw "rectangle 0,0 $(identify -format "%w,%h" $input_image)" \
~/.xfdesktopWU_dimmed.png
fi
else
/usr/bin/xfconf-query -c xfce4-desktop -p "$line" -s "$wpImage"
fi
done
...However, for the logic to work correctly, we need to somehow monitor dbus color scheme signal changes as well.

Due to gala rendering it by applying opacity over wallpaper instead of altering an actual image, it's impossible to get the dimmed variant by just using the actual file path. I think it should be possible to implement using imagemagick, but sounds like way too much hassle for now.
