[UWP][C++] MFTrace not showing many calls when debugging

I'm using mftrace to debug a UWP app that uses Media Foundation. The problem however is, that many calls are not showing up in the log.

For example, I'm logging MFPlatExport which should hook all exported functions from mfplat.dll, right?

Well, functions like MFCreateDXGISurfaceBuffer, MFCreateVideoSampleAllocatorEx or MFCreateEventQueue never show up in the log, even if I trace at the highest level.

Am I doing something wrong or is the tool just too old for this?
