That sounds like "Eyes of Amber", by Joan D. Vinge, from the short story collection of the same name. It has the jewelled wings:
His movements were ungraceful; she remembered how the jewels dragged
down fragile, translucent wing membranes and slender arms, until
flight was impossible. Like every noble, Chwiul was normally
surrounded by servants who answered his every whim. Incompetence,
feigned or real, was one more trapping of power, one more indulgence
that only the rich could afford. She was pleased that the jewels were
not of high quality.
As well as the "demon eyes":

The basic storyline is that an unmanned probe from Earth lands on Titan and discovers an alien medieval-level society. The probe has detachable viewer cameras, one of which is picked up by one of the aliens. The watchers on Earth are following this alien's story as she tries to gain back her queendom which was stolen from her. The alien's story has become so popular as a mass-market reality-TV show, it's funding the space program.

exciting episode! I think Reed will love it; that's what I think." He
pointed at the newspaper lying on the floor beside his chair. "Did you
notice we've slipped to page three?" T'uupieh had fed the probe's
hopper some artifacts made of metal—a thing she had said was only
known to the "Old Ones"; and the scientific speculation about the
existence of a former technological culture had boosted interest in
the probe to front-page status again. But even news of that discovery
couldn't last forever . . . "Gotta keep those ratings up, folks. Keep
those grants and donations rolling in."
Interesting side-note: this story was first published in 1977, well before "Meercat Manor" or the reality TV craze.
