There's no distinction between the "desktop" and "mobile" versions of GNOME Web. It's literally the same code (compiled for the appropriate processor architecture), just at a different window size.

So, all options shown in the preferences of the desktop version will automatically be shown in the preferences of the mobile version?

You can test it by shrinking the Epiphany's window while running its latest version on desktop.
