Perhaps you could inform me about something I’m disputing about on another site. When the steam condenses, does it thereby heat up its container/shared atmosphere (if any) in direct transfer of latent heat energy?

Steam condensing is just like sweat evaporating in reverse. So whereas evaporation extracts heat from its surroundings (like your skin) to overcome the latent of vaporisation. Condensation will return exactly the same amount. So water vapour condensing on a cold window or bathroom mirror will warm it up slightly.
