There are different ways which will give you different answers in
different cases:

- you can check the `display` parameter of the selected frame (should
  handle the `emacsclient --display` case).
- you can check the `environment` parameter of the selected frame
  (probably not very useful).
- You can check the `env` parameter (with `process-get`) of the proc
  object that represents (on Emacs's side) the emacsclient connection.
  For that you'll need to get access to this proc object, but I don't
  know offhand how to.
