An advanced civilization, by definition, would not be dependent on starlight.
Or planetary surfaces.

Where else could they possibly get energy from? Planets can be replaced by orbitals, but there's no way to replace the sun.
Even extreme primitives have magnetic-confinement fusion.

Ah ok. That makes sense. In that world, they can even use miniature black holes once they can stabilise and capture them in a field, to generate energy.

Who's to say that the amount of red we're seeing now isn't exactly what you're describing? Maybe if we lived in a barren galaxy, we'd see a lot more _blue_, as stars shone unencumbered by matrioshka brains.
We'd see more red than we do - more heat and less light. Civilization produces heat. Advanced civilizations would presumably convert starlight to energy and produce waste heat.
