How do I confirm whether a specific Bios update is installed?

Dell emails me a notice that a Bios update (Trust Device Agent version 3.7.89.0, A27) is available for my XPS 15 9500.

I dutifully head over to Dell support and select "Check for Updates" and the system responds "Your system is up to date".  I then use the "manually find a specific driver for your XPS 15 9500" function" and see the subject Bios update is listed.  But when I toggle on the "Show downloads for only THIS PC " function, the subject update is not listed.

The inference to me is that the driver is already installed but I am not confident that is the correct conclusion.

How do I confirm that inference one way or the other?
