If all that you want to do is drop the +91 I would craft the transformation like this.
There is no need to go specific on the transform mask or with a number of X's in the match part. That just complicates stuff IMHO.
Create a css with only calling party partition and on gateway select this css from the calling party css option and not the normal css option.
Just a control question, have you done the obvious step to restart the SIP trunk for it to activate the changes you made?
Can you please share a screenshot of the pertaining part of the trunk configuration so that we can verify it?

As you wrote that you want to affect the presentation for inbound calls from PSTN on your phones you should put it in the incoming section of the trunk.
Instead on phone, apply this on the device pool and restart the device pool..
Remove the CSS from the trunk.
IMO it’s better to affect the calling and if needed called number as early in the call flow as possible. So based on that it would be better to put the transformation on the trunk or possibly even better to modify the numbers with translation rules on the gateway itself.
The phone settings part has these setting options.
- Caller ID For Calls From This Phone
- Connected Party Settings
- Redirecting Party Settings
None of these are the setting that you'd need to alter on the device pool to affect the calling number on a device. What you'd want to set is Calling Party Transformation CSS under Device Mobility Related Information as you yourself have figured out.
