Why is output from gsettings list-recursively slightly different when run from cron

I have run gsettings list-recursively locally from the terminal while logged into X11 on Ubuntu 20.04. Then I also configured a user-based cron job to run gsettings list-recursively from the cron and save it into the file. When I compare contents of those files they are slightly different: some entries have different values. But some entries which I know I changed do match. Why are there differences?

I have read around about DBUS_SESSION_BUS_ADDRESS but I am not setting it for the cron job and it seems gsettings still works (but output is slightly different).
