Gyro & Accelerometer Linearity Specs for ISM330DHCX and LSM6DSM

I'm working on selecting between ISM330DHCX and LSM6DSM for some products under development. The one key sensor specification I can't find the data sheets is Typical Gyro/Accelerometer Nonlinearity (Best-fit straight Line) (% of FS).

Can anyone point me to these specifications?

    Hi @SLi.9bert​ , Nonlinearity is a parameter that is typically not present in the datasheets, but we can share characterization values on a small sample set, both for 3-axis axl and 3-axis gyro. Regards

    Thanks! Are these values the same for the ISM330DHCX and the LSM6DSM?

    Basically yes on the same FS specs. These data refers to the LSM6DSM sensor, but very similar for ISM330DHCX. Regards
