Solved by changing the path on the Blue Iris Configuration Window from /onvif/profile1/media.smp to /onvif/H.264/media.smp
Details
Blue Iris' Find/Inspect returns the camera's first profile, which is MJPEG and limited to 1 fps. Here are the Blue Iris Find/Inspect results:
/onvif/H.264/media.smp or /onvif/Profile2/media.smp give the same results.
Profile customization
The camera web viewer supports adding profiles. I added a profile named BlueIris, with codec H.264. The Configuration path = /onvif/BlueIris/media.smp or /onvif/profile3/media.smp
The first two profiles (MJPEG and H.264) are considered default and cannot be deleted or renumbered. Profile3 is MOBILE and can be deleted. If you add a profile, MOBILE becomes profile4 and the added profile becomes profile3.

Using that path created the problem.first profile is a5e5e40b-e2d3-44d7-bd60-a0a3c4454cd0

The camera's profile2 is H.264 and supports 30 pfs. Note that you can reference the profile by name (H.264) or by number (profile2). Either works. So/onvif/H.264/media.smp or /onvif/Profile2/media.smp give the same results.
