Low-Level SDK WMI Client Policy Question

I'm trying to automate certain processes with the SDK via Powershell and WMI.  I've made some great headway but I'm stuck on a particular function I'd like to create.
 
I'm attempting to create a Powershell function that checks both a client's policy and the server's policy to see if they're in sync.  Basically, I'd like to tell if when I refresh the machine policy if the client is actually going to get a new policy before it happens.  Does anyone know how the client can tell if it needs to update it's policy?  Is there a version number stored somewhere on the client and the management point that it checks?  That would be nice.
 
Anyone have any advice?

Yes, I know this is an old post, I’m trying to clean up older posts that are unanswered.
Did you ever figure this out?
