Actually that's not exactly true. It's possible to start bash as login
shell but - will be absent. Quoting relevant part of manual:

"A _login_ shell is one whose first character of argument zero is `-',
or one invoked with the `--login' option."

Better way to check if shell is login is:

 $ shopt | grep login_shell
login_shell     on
