bool enabled = a11yAlwaysOn || a11yStatus->screenReaderEnabled();

Using screenReaderEnabled is not a proper way: that property only means
that the screen reader should be started on session startup. isEnabled
should be used instead, see its declaration in

./src/platformsupport/linuxaccessibility/dbusxml/Bus.xml

That one is set by Orca when it is started (either explicitly by the
user or automatically for the session), but also by other accessibility
tools (such as focus tracking for zoom support in compiz).

Yes, but that is gnome-specific.
