Honestly: don't know.
My experiments never had a dependency on linearity.

Took some spectras from heat pumps, airplanes and a helicopter.
So the sensor isn't blind within this range.
A long time ago I used a hot wire anemometer to measure flow up to several hundred Hz, but that was an expensive instrument being read by an expensive National Instruments acquisition platform. This is a cheap, self-contained device. Go Sensirion.
I wonder whether the frequency limit ends up being set by the ADC or the physical sensor. I’m also curious how the Sensirion sensor detects the sign of the pressure difference.
