I haven't, now that you mention it. Perhaps not their best documentary but the stereoscopic photography inside the lunar capsule and on the moonscape conveys certain story points visually that are lost in the flat version. For instance the stereoscopic photography demonstrates why the astronauts lose visual perspective on the moon. They can't tell how far away or how close things are. A crease in the ground at their feet could be a vast canyon or a shallow trench. Without recognizable shapes in an atmosphere, they can't tell. In the flat version, this point is lost. On the big screen it was physical.
Regarding SPACE STATION 3-D, one of the most startling scenes is the astronauts rehearsing under water. You feel the consistency and the thickness of the water on a screen three stories high in 70mm 3-D. On the flat panel the sensation is not as acute, but if your mind is open to the visual subtleties you'll get it.
All the Imax 3-D blu-rays are excellent and worth buying. Every single one. At 45 minutes or so they don't overstay their welcome but you'll know you've seen something special. Here is an amazon search for the words Imax 3-D blu-ray:
For some reason Star Trek comes up in the list, but you should ignore that piece of junk and stick with the Imax and Costeau documentaries. They are worth every penny.
