I was only 8 years old, so I don't remember but I've looked at the pics from that mission and I don't remember seeing 'earthrise' as they call it.

Two German made 70-millimeter Hasselblad cameras were used on the mission-neither were pressurized to prevent the chemicals in the celluloid from smudging.

To keep the inside of the suit at about 80 F it would have to work as you say.
The other thing is, if this pic was taken back then it would have been in every teen agers room on a poster, and in every science class. Maybe they released this thjree years ago, finally, that's when I found it.
Getting rid of waste heat was indeed an issue. Their backpacks on their space suits contained a clever device to keep them cool. When water sublimates from ice into water vapor in vacuum, it absorbs heat. They had a pump that dribbled water onto a sort of grid called the sublimator (where it froze in the dark) and then sublimated into water vapor in the vacuum. More water went through a heat exchanger in the grid. This water was cooled by the sublimating water and went into tubes in the space suit that kept the astronauts cool.
I’m not sure how cooling worked in the LM, but it was probably similar...hope that explains some things..it seems feesible to me..
There's a lot of questions regarding the missions, the cameras as I mentioned and the cooling equipment on their backs. The tech of those days would have required an ac unit on their backs to be almost as large as a small window ac unit. 120's-160 degrees F on the moon. Dark side is -200'sF
Here is the whole lot of photo's & links to them:-
