No, looks like it's falling in altitude?

I was looking at that too. On one of the other camera angles, you can see a monitor in the Flight Control Room that shows the satellite, and the fairing. And that doesn't look like it's separated.
It'd make sense for the under-performance. (Added fairing weight, even with nominal stage burn)
Haven't wanted to be wrong in a while now, but I am.
