While heat can be indicative of how warmed up an amplifier is, the corollary is not necessarily true.
I would imagine it is more to do with capacitors stabilizing and tubes and semiconductors reaching their operationally optimum parameters. Therefore, applying heat is most likely not conducive to expediting peak operational conditions.
