Yes I remember that very discussion :-)

Something I worked out since then, is that a large part of the problem 
is the mismatch between the field-of-view of your image, and the FOV of 
the physical device you are viewing it on.

On my desktop monitor I get an hFOV of about 35 degrees, I suspect if 
you render an image showing the sun with an hFOV to match, it will look 
a more realistic size.

Note that in certain 3D games (especially car racing simulators) it is 
very important to get the virtual FOV to match your real life display, 
otherwise it messes up all your judgement of depth and perspective, the 
problem with the sun size "looking wrong" is just an extreme example of 
this.
