For VSE you can check the virusScan console on the client manullay to check the policy that is applied i.e Access protection: open VirusScan caonsole>double click on Access Protection>check categories.
not quite the answer you want but for an easy "have a check if the new policy is assigend" you can mark the system within the ePO System tree, click on action and let you show via "View assigend Policies" which policy is assigned to the system. But nothing like the revision ID for DLP I am afraid :-/
Policy number is available only on DLP product, If you need to compare VSE policy locally with ePO check below machine registry keys.
