I recently noticed that a recent update to the TinyCam IP camera app added support for Blink cameras. I am not tech savvy enough to understand how the developer was able to do it, however I was curious if it may be something that Blue Iris could incorporate as well.

From what I see, Blink cameras are not Onvif. That would seem to prevent BI from supporting. If you have one, you could install the onvif devicemanager and check if it "sees" it.
