There's no stealth in space. Any sort of running electronics or photovoltaics will emit heat that can be easily picked up by spaceborne sensors. The strategic advantage for military satellites is going to be the fact that Starship can launch literal orders of magnitude more of them than the launch systems of rival countries, not the fact that they're painted black and thus marginally harder to spot from the ground with Mk. I Eyeball.
