How to determine whether a file has changed through the VersionControl.Provider?

Hello, I am writing an editor script and one of the things I need to assess is whether or not a particular file has changed.

Not sure if it matters but our version control system is Perforce.

I did some testing using the Provider.RevertIsValid() API and here are the results (where at least one or two of these cases seem incorrect):

Here is what the p4 command line app reports when I try to revert the files where again the .meta is not changed but the .h was changed.

λ p4 revert -n -a .\Wwise_IDs.h.meta
//depot/DemoV2/Assets/StreamingAssets/Audio/GeneratedSoundBanks/Wwise_IDs.h.meta#1 - was edit, reverted D:\src\P4ROOT\PlutoP4\DemoV2\Assets\StreamingAssets\Audio\GeneratedSoundBanks

λ p4 revert -n -a .\Wwise_IDs.h
D:\src\P4ROOT\PlutoP4\DemoV2\Assets\StreamingAssets\Audio\GeneratedSoundBanks

If it helps here is the code I was using to generate the above results and I would just change which enum and asset path I passed in,

         if (!Provider.enabled || !Provider.isActive) { return false; }
         var asset = Provider.GetAssetByPath(assetPath);
         if (asset != null)
         {
             var revert$$anonymous$$ode = Revert$$anonymous$$ode.Normal;
             var revertStatus = Provider.RevertIsValid(asset, revert$$anonymous$$ode);
             return revertStatus;
         }

I also tried to experiment with using DiffIsValid() using an AssetList I constructed from this single asset and it returns true for either the modified or unmodified file.
