Start application with modified X11 properties

Hi,
I run GNOME with a light colored theme, yet some applications (name it, blame it: spotify) have a hardcoded dark UI.
After starting the app, I can use xprop to change the window decoration theming by changing a X11 property, ofc changes are lost after the application closes.

xprop -f _GTK_THEME_VARIANT 8u -set _GTK_THEME_VARIANT dark -name "Spotify"

Is there a way to specify this tweak on startup? So i.e. I'd like to use something like

magicXtool -set_GTK_THEME_VARIANT=dark applicationName

that I can put into my .desktop files for launching.
