SVP / SmoothVideo Project a video renderer of sorts was crowdfunded a while back and added Ambilight support for some devices back in 2015 just not Hyperion, they support a large number of players:

If we can get them to support Hyperion as well this opens it up for native playback without needing any video capture or plugins as it grabs it at the rendering end
Will contact them today and see if they are up for adding Hyperion to the list of supported devices:

Wondering what you guys think about this idea and if more are interested
