The only easy possibility I see is going to about:flags and setting MediaFoundation for Clear to Enabled. That switches to a Windows-provided video decoding and display pipeline that (ideally) should be equivalent to the WMF decoder.

As a note, I believe that same system is also being implemented into Firefox by :alwu in Bug 1752052, so if you set media.wmf.media-engine.*.enabled to true in about:config, that'll allow a direct comparison of that mode of playback.
