No, it's the other way around. Writting to dconf goes through a proxy
service and the client talks to the server using dbus, so with the
gsettings interface your snap can contact the desktop service and the
write is done in the real-session's dconf database.

Reading is done by opening a file in the user directory though and that
doesn't work "out of the box" from inside the snaps because your code is
going to see the private-snap-dir and not the real system one.
If you use the desktop common part it has a hack for that though

You should rather look on your desktop using e.g dconf-editor
