It's an outlier sure, but how extreme is unclear.
France being a developed nation (say 5 - 10% of global population at the time). Jeanne being upper middle-class (again say 5% of France).
How many with the potential to live a much longer life did not do so because they lacked Jeanne's social advantages? Or did actually live long, but were not documented.
If we could model these premature deaths and fit them into the curve, how much less extreme would Jeanne appear to be?
What you are proposing is basically exactly what the researchers did in their paper, just comparing the data looking at people who were already supercentenarians, not the whole population at large, and found that Calment was a widely improbable outlier even just among this group.
