here is what an o3 filter (8.5nm) looks like on a (colour) dslr.

looking at the G and B channels, the signal is WAY stronger in the G - but I'm not sure if that's because it has double the pixels in the bayer matrix... - either way its probably 5x plus richer in G (total guess)
not sure that helps at all. of course its rare to have o3 just by itself so a light pollution filter/osc will likely give a different hue.
