Yeah, it looks like even VimEnter fires earlier. I checked in the
debugger, v:termrbgresp is only set once the main_loop has been entered.
I think I remember a patch that moved the logic later in the vim
initialization phase, so it might be on purpose.

And TermResponse is only fired for when the v:termresponse variable is
set, not for the v:termrbgresp or v:termrfgresp variables. Not sure, if
it would make sense to fire TermResponse autocommand also for the other
v:term variables.

So the only workaround would be to start a timer that checks your the
values after startup.

Best,
Christian
