You dont need to examine the contents of http traffic to do what many services call DPI.
you can still read unencrypted traffic, like most DNS. Or even without that, you can frequently tell from the endpoint IP who someone is talking to, and what types of applications from port numbers used. Etc.
If you're torrenting, for example, that's pretty easy to see.
Still not DPI. Regardless of what other manufacturers or devs call it.
At best it's a network monitor. Literally pihole can give you most of those stats as well.
