No, not really.
We are talking here of the first time a short burst of only a few minutes was detected from a source not previously known.
Distant galaxies with super massive black holes in their center are a well known source of this kind of gamma radiation. Known as active galactic nuclei and especially blazars

It's not hard to get more total energy released, just by being bigger. To concentrate more energy into individual photons requires more intense processes. A black hole crashing into a magnetar would cause unusually intense activity for some while.
