It is not possible to do this with gsettings, as the option simply does not exist. There is extensive documentation on gsettings and the internals of the program at the official Gnome site.
However, there is an interesting project at github called gsettings-info that does exactly what you ask. It is a script that queries information about either schemas and/or keys from the gschema information and returns the same data about them that is displayed when you use dconf-editor.
You'll requiere Git and git xsltproc (library that it uses to read the gschema information)
sudo apt install git xsltproc
Obtain the program with:
git clone git://github.com/jmatsuzawa/gsettings-info.git
cd gsettings-info
Now you can run the script
./gsettings-info <command>
You can either run it from the home folder (and occasionally update it by going to the folder and using git pull), or install to the system or place it in your ~/bin folder so it is available by just entering gsettings-info.
If you are running it from the downloaded folder, entering ./gsettings-info help will give all the options, as does the README and the information at the Github page.
You can find much information on both the schemas and keys. Here is an example of how to find data about certain keys. This assumes it is run from the downloaded folder, and so ./ is needed to run the script.
To find out details about the particular keys of the chosen schema, enter:
./gsettings-info desc org.gnome.gnumeric.autocorrect
which returns:
init-caps: Autocorrect initial caps
init-caps-list: Autocorrect initial caps
first-letter: The autocorrect engine does not correct the initial caps for words in this list.
first-letter-list: The autocorrect engine does not correct the first letter for words in this list.
names-of-days: Autocorrect names of days
replace: Autocorrect replace
To show defaults and information for a particular key, use:
./gsettings-info show org.gnome.gnumeric.autocorrect init-caps
which returns:
KEY: init-caps
TYPE: b
SUMMARY: Autocorrect initial caps
DESCRIPTION: Autocorrect initial caps
DEFAULT: true
This seems to be exactly what your are looking for, and is about the only way to show this information on the command-line instead of in dconf-editor.
Found the answer by myself in the end.
sudo cp ~/.local/share/gnome-shell/extensions/extname/schemas/org.gnome.shell.extensions.extname.gschema.xml \
/usr/share/glib-2.0/schemas/ &&
sudo glib-compile-schemas /usr/share/glib-2.0/schemas/
Copy and compile the schemas in ~/.local/share/gnome-shell/extensions and gsettings will be able to work with them.

In fact
dconf-editordoes show the keys and values of each profile, in the subdirectories of/org/gnome/terminal/legacy/profiles:/. Their names are UUID's, with a colon prefix. But the default profile only shows up if it's been modified.If you still want to use the command line,
dconfseems like a better choice, since as far as I can tell,gsettingsdoesn't have access to the individual profile settings, only the default settings for new profiles (not the settings of the default profile). Though on the other hand,dconfdoesn't seem to have access to the default settings.dconf
