A shell in a Matrioshka brain (more generally, a Dyson sphere being used for computation) reradiates 100% of the energy it captures, just at a lower temperature.
Yeah, the energy radiated to infinity only gets reduced if it’s being used for something long-term, like disassembling the sun or sending off energy-intensive intergalactic probes.
