I think this would be the case if the usual four dimensions were involved.
If a further dimension came into play, it is possible to imagine the
surface of the expanding wave having a large (and possibly increasing)
area, while the energy of the photon is transmitted at a specific,
point-like location.

We already see evidence of photons of different energies having different
cross-sectional areas to their wavefronts.  High energy gamma rays interact
with nucleons or even constituents of nucleons, but not atoms as a whole.
Lower energy gamma rays interact with an entire nucleus but not individual
nucleons.  Yet lower energy photons interact with and eject electrons from
atomic orbitals but are transparent to nucleuses and nucleons.  Photons at
even lower energies are transparent to atoms but interact with antennas and
other macroscopic bodies.  In this sense there is an ever-expanding area of
interaction as the photon energy decreases, and vice versa as the energy

The limiting case are perhaps the photons involved in extremely low
frequency (ELF) radio waves [1].  Frequencies in the 3 Hz range correspond
to wavelengths of 100,000 km.  In my mind that entails a very large area
wavefront.  I doubt there is a point-like photon involved in this case.
