I found the lens for crop factor 1 and Canon EF mount. Your A6300 has 1.534. You could copy this stuff and edit the mount and the crop factor for the profile to be applied, but most likely the correction won’t fit the aps-c sensor.

It seems strange if the crop factor is 1 and taken with 750D.

Good point, this doesn’t look correct.
I would simply test it. Set the camera to generic, crop-factor 1.0. Then choose the lens and see what it does to a photo of some straight grid lines. If it’s fine, edit the XML for it to be auto applied. You would have to redo this after DT updates.
Or make a module preset for the lens.

I have a similar problem with one of my Sigma lenses being identified incorrectly. The simple solution for me was to make a preset to select the correct lens.
