This is a basically 'academic' question --- to try to understand better the configuration system innards.
I understand that the dconf system is the new configuration system in gnome3 that has replaced the (deprecated) gconf; this is quite clear from Gconf, Dconf, Gsettings and the relationship between them.
It seemed to me that the programs
dconf-editor where just two different way to access the same dconf database, which is corroborated in
What is dconf, what is its function, and how do I use it?
EDIT: I discovered that someone noticed it as a difference in case in some schema name, see here --- Are dconf schema names case-sensitive?; but it seems that the differences are not restricted to that. In one of the answer there is an example of mismatch, but I didn't find an explication of why.
But lately I discovered that the keys accessible from
dconf-editor are not the same. For example, settings for
vino are in
org.gnome.desktop.remote-access (see screenshot below) while in gsettings they are under
org.gnome.Vino. There is some documentation that explain the difference?

org.gnome.Vino authentication-methods ['none']
org.gnome.Vino disable-background false

No such schema 'org.gnome.desktop.remote-access'
But in dconf-editor:
