I would expect quartz to do one of three things, although others are possible:

* ignore format changes entirely,

* report the new format in the sample itself, via IMediaSample::GetMediaType(),

* reconnect the downstream pin.

In this case, as I understand, there's no real format change, it's just that GStreamer gains a bit of information more asynchronously; in that case nothing should happen.

Probably we shouldn't even be reporting a format change if the translated wg_format doesn't change.
