The cold inside surface is only exposed to a sealed area that is filled typically with argon gas to reduce re-radiation but it is also dry so there is no moisture ( water vapor) to condense on that surface (the inside surface of the outer pane of glass).
Technically it is more like convection or maybe conduction?
One can imagine the old video game Pong, and the pong balls carry the heat from one side to the other like a pack mule.
The argon pong balls are slow and carry heat from one side to the other in each bounce.
The helium pong balls move faster so we get more bounces per minute.
So if each load of heat the heat on the mule is the same, we simply get more loads carried over time with helium pong balls than with the argon ones.
The fellows talking about garbage bags amd not opening the box, sort of doesn’t make sense to me, as I am used to seeing the devices wrapped in a bag inside of the box with a little bag of magic desiccant crystals.
If it is one of those similar deals here, then just keep that bag sealed.
The box and Styrofoam shipping protection, only insulates it to delay the warming.
