I don't believe cryogenic treatment of a vacuum tube does anything WRT "outgassing". The internals of properly mfgd receiving tube are heated to incandescence while on the vacuum pump. This process causes most gasses adsorbed or clinging to surfaces to become "airborne" and it increases the effectiveness of the pumping process.
Cryo techniques applied to parts not specifically designed for them strike me as one of those episodes of life where it "works" because it's expected to work.
