Dramatically different scale.
The imaging satellites with the mirrors and telescopes are more dynamic and in eccentric LEO orbits at a similar height to the starlink sats.
see: https://en.wikipedia.org/wiki/KH-11_KENNEN (and the heading Resolution and ground sample distance indicating the close approach height being closer to earth's surface than typical starlink sat).
The above comment about geostationary orbits is confused .. the spy sats with mirrors relay their data out to geostationary relay sats and then back to earth ground stations.
If you're curious you can read more in the wikipedia link (and other references) I linked in a peer comment.
