The softness is much more apparent on the 720p channels than it is on the 1080i channels.
Geometrics have a lot to do with detail/softness, but color/contrast also affects it more than might be obvious. Edges are tight, or abrupt, transitions between different colors and luminance levels. A good calibration smooths and clarifies all color/luminance transitions. The same tweaks that improve banding issues - i.e. large area color/luminance transitions - typically improve detail also (maybe think of it as "dirty" transitions vs "clean" transitions).
I'm guessing some HT calibrators only deal with color/contrast. Just ask up front if they also examine/tweak geometrics if you want to cover your bases. Both the calibrators I've seen (at work and at home) addressed both color/contrast and geometrics.
I'm also guessing any geometric adjustments would be in the service menus - just got my GT50 yesterday so I haven't had a chance to dig into it those yet. Not even sure if I will
