As I expected, I just didn't catch any mention of this during the Live stream, I figured I might have missed some mention of it since since I tuned in right about when they started getting data frames from the DSN.

I figured the team had decided to uplink only the most essential frames for this test flight (spin up, hover, and spin down) and send the low-res preview versions of them back in order to get the data back as fast as possible before a much slower upload of the full mastcam higher resolution video frames.

Whats extra amazing here is this is High Definition (possibly even in 3D) video sent to us from a nuclear powered rover on Mars!
