I don't think we know about this. The two possibilities are:
The first possibility is obviously more attractive to us, and it's not uncommon for Volvo to do that, less versions of software for them to maintain! But there is no guarantee they have done that.
But you could probably figure out, if that is the case for your car, by enabling configs, then see if those things work! You may have already, but stick with me here....
When was the last time your XC90 visitied a dealer or was connected to VIDA and software updates done (Total Upgrade in Volvo-speak)? You would want to know that your car was updated at least after those features were released, and preferrably the more recent updates were installed, the better likelihood that these features are present an able to be turned on with config.
Now that said, what items have you enabled, and what have you done to check if they are enabled? Some items I think are obvious, like LKA with steering assist will have settings you can see in Sensus menus, to turn the steering assist and vibration on and off. Others are not so easy to confirm, like say "Run off road prevention" there is no button or setting for that that I recall...I don't know what you would do, try to run off the road??....
- Volvo has updated the software (via Total Upgrade) in all cars for these capabilities, and the accessory install merely enables additional features
- There are some software components not installed in the vehicles without the "upgrade" that need to be installed for those features to work
