This is too hacky as for my taste.

I'd rather use :ignore: tag from ox-extra:

* This is frame 1
* This is background wrapper, heading title ignored :ignore:
#+begin_export beamer
{\usebackgroundtemplate{\includegraphics[width=\paperwidth]{kitten.jpg}}%
#+end_export
* This is frame 2
* This is background ending :ignore:
#+begin_export beamer
}
#+end_export

The above exports to

\begin{document}

\begin{frame}{Outline}
\tableofcontents
\end{frame}

\begin{frame}[label={sec:orgea52eac}]{This is frame 1}
\end{frame}
{\usebackgroundtemplate{\includegraphics[width=\paperwidth]{kitten.jpg}}%
\begin{frame}[label={sec:org39b6485}]{This is frame 2}
\end{frame}
}
\end{document}

Best,
Ihor
