That is also my belief. Unfiltered magnitudes also correlate very well indeed with Gaia-G magnitudes. This should come as no great surprise …
That’s why I generally quote Gaia-G magnitudes for objects on unfiltered images I’ve taken. Please note, these are NOT images taken for photometric analysis, for which I almost always use V or Sloan r filters.
