The charts in that paper also make it seem that n95 *typically* has a much better seal on the face which is worth noting.
I also wonder if the breathability you're measuring affects filtration, given imperfect fit. I would imagine that worse breathability would cause more air to flow around the mask rather than through it.
For example I found this study on beard length which made me reconfigure my facial hair: https://www.nature.com/articles/s41370-021-00337-1
