It doesn't have to be sheer luck: Emacs resets some display-related
parameters after it reads the init files, precisely to cater to the
cases such as this one.  I don't know if this parameter is one of
those that benefit from this, but it might be.  One example of
settings that definitely are acted upon after reading the init file is
default-frame-alist.
