Is it also a relative improvement of the energy conversion into electricity vs. into heat? Intuitively the photons energy will be partially converted into both (conservation of energy) and this efficiency improvement seems like it would skew that ratio into favor of electricity generation.

I would think so, since the reason the efficiency was less than 100% before was that some of the electrons were being recaptured rather than emitted from the detector. On the other hand, the article didn't say anything about the amount of energy captured. It could be that more of the photon's energy is converted into heat, with the remainder being spread across more electrons.

Ah, that's a good point. I wasn't thinking about the relative energies of the electrons themselves.
