I'm assuming the Ram Air Turbine gives extra evidence of a dual engine failure (or at least the engine that generated power). Engine spools down, power is lost, air turbine needs to be deployed.
Those things are tiny and very transparent (since it's pretty much a propeller) and video compression, plus it's a video of a screen, will eat it up against a clear sky.
And here's a YouTube video showing a Ram Air Turbine (RAT) being deployed on a 787 for comparison: https://www.youtube.com/watch?v=oFBCGf50Trc&t=69s
