Yes, seems so.

From emacsclient(1)
-s, --socket-name=FILENAME
use socket named FILENAME for communication. This can also be
specified via the EMACS_SOCKET_NAME environment variable.
> This can be the same NAME passed as the --daemon=NAME argument to emacs.
From emacs(1)
--daemon[=name], --bg-daemon[=name]
Start Emacs as a daemon, enabling the Emacs server and disconnecting
from the terminal. You can then use the emacsclient (see
emacsclient(1)) command to connect to the server (with optional name).
So if I use
>> $ emacsclient -s /run/user/1000/emacs-default -F '((name . "default")
>> (title . "USER@HOST"))'
then I use socket it means I use '--daemon' for emacs. Indeed I use socket
activation provided by systemd.
From emacs(1)
--name=name
Specify the name which should be assigned to the initial Emacs window.
This controls looking up X resources as well as the window title.
-T name, --title=name
Specify the title for the initial X window.
When Emacs is run by just running 'emacs' and querying X properties
$ xprop | grep 'WM_CLASS\|WM_NAME\|WM_ICON_NAME'
one gets
WM_CLASS(STRING) = "emacs", "Emacs"
WM_ICON_NAME(STRING) = "emacs@smoon.bkoty.ru"
_NET_WM_ICON_NAME(UTF8_STRING) = "emacs@smoon.bkoty.ru"
WM_NAME(STRING) = "emacs@smoon.bkoty.ru"
_NET_WM_NAME(UTF8_STRING) = "emacs@smoon.bkoty.ru"
While running Emacs by
$ emacs --name default --title USER@HOST
one gets
WM_CLASS(STRING) = "default", "Emacs"
WM_ICON_NAME(STRING) = "default"
_NET_WM_ICON_NAME(UTF8_STRING) = "USER@HOST"
WM_NAME(STRING) = "USER@HOST"
_NET_WM_NAME(UTF8_STRING) = "USER@HOST"
In other words, emacs has option to set instance name (first string of
WM_CLASS value) and set window title. On the other hand emacsclient doesn't
have such option so it is (seem) impossible to set 'instance'. I wonder why it
doesn't have such options.
I read Emacs and Emacs Lisp manuals about frame parameters but don't get if it
is possible to set instance (and possibly name) using frame parameters. I
tried to use -F option but don't get desired result.
