Hmm. From the way I understood it - no.
Virgin have the ability to send whatever config profile they like to your modem - as the speed uplifts show.
So I always assumed that this is all they did - you hit X threshold they send Y config profile which sets your modem to Z speed. After the time period is up they then send the config profile that matches your original tier.
I'm pretty sure people have posted on here that that is the case - because you can see it in the modem pages
Again - this was just how I think it works.

If anyone wants go through it and tell us - there is a full 'Subscriber Traffic Management for the Cisco CMTS Routers' manual here

But from a quick scan (and if I understand it correctly) it seems to use QoS profiles rather than any DPI

In fact part of it says:
The STM feature enables service providers to identify and control subscribers who exceed the maximum bandwidth allowed under their registered quality of service (QoS) profiles. STM works as a low CPU alternative to Network-Based Application Recognition (NBAR) and access control lists (ACLs).
