I realize we will never set it for ourselves.

All this cool shit in space, we will only ever see pictures.

Because all those pictures aren't real pictures. They are taken with tons of filters. You see warmth, energy, etc. Those pictures aren't pictures of light. You couldn't possibly see it with your eyes. Space is pitch black.

They are real pictures. Those pictures are of light, HST is an optical telescope. No space is not pitch black, the stars are even brighter outside the atmosphere.

iirc a lot of those photos are long exposures and that if you were to look with your fleshy man-eyes these things wouldn't be nearly so exciting to look at

Yeah, but we're really far away too. If we were closer (and blocked out light from other sources, we see dim objects near very bright objects by covering up the bright object), some structures would be brighter, to an extent.
But nebulae are so big and diffuse they've be invisible up close. The face of OP's unicorn is about a light year long.

The IAU currently does not recognize space-unicorn as an alternative to light-year.

That doesn't mean they aren't real or aren't visible light.

They're definitely *real*, but they're not as visible as the photos make them appear. Most of those awesome nebula photos are long exposures, yes, but they're also composites of infrared, x-ray, and visible light, with some coloration and hue/contrast added to make them "pop." It's a real thing in the photo, but it's not the "natural" way it looks.
