Confirmed with the RPi people, OMX_IndexConfigVideoIntraVOPRefresh is not supported:

https://github.com/raspberrypi/firmware/issues/462

It looks like OMX_IndexConfigBrcmVideoRequestIFrame might do the trick, but the question then becomes is the existing code wrong and OMX_IndexConfigBrcmVideoRequestIFrame should be used instead of OMX_IndexConfigVideoIntraVOPRefresh, or this is a case of where some platforms use the one and some the other?
