The OS changes the title bar color etc., but such a change would let
Emacs adapt frame contents, for example by changing the active theme.
To give a concrete example, I have the snippet below in my init file,
evaluated when I'm running Yamamoto-san's Mac port:
(add-hook 'mac-effective-appearance-change-hook
#'(lambda () (pcase (plist-get (mac-application-state) :appearance)
("NSAppearanceNameDarkAqua" (modus-themes-load-vivendi))
("NSAppearanceNameAqua" (modus-themes-load-operandi)))))
