Path to wallpaper is not displayed anymore on Sequoia

I configured my Mac to show different wallpapers on each MacOS Space. Until now, I had the path to the wallpaper shown on the screen as well. I had done this by setting defaults write com.apple.dock desktop-picture-show-debug-text -bool TRUE;killall Dock However, since my update to MacOS 15.1, the path is not shown anymore, even after re-issuing the defaults write ... command. Any idea of what I could do to find out the path to the wallpaper in a certain MacOS Space? Note that defaults read com.apple.dock desktop-picture-show-debug-text displays 1, from which I conclude that the value was indeed set correctly. It just seems that Sequoia ignores it.
