Most new users end up disabling the toolbar, menu bar, scroll bars, etc. and only then does it look the same in the terminal. Even then, many themes and packages frivolously change font sizes or switch to non-monospace fonts in some GUI contexts, so for users that like the uniformity of the interface you need to do extra work to disable these features.
(I personally like the terminal aesthetic, and configure the GUI to look like a terminal. That basically required advising load-theme to loop over all faces and disable font properties I don’t like after each theme change…)
