Above 15hz, all three settings has identical response.
Note: each graph was measured after each Audessey recal with Aud on and DynEQ off.
Audyssey is throwing things off, since it is applying variable EQ. Measure again without Audyssey.
Low damping has a steeper filter slope, which cuts power-intensive low frequencies more aggressively for more headroom and adds a bit of ringing (smear).
"Full body" can be a nice way to describe ringing or sometimes distortion. Generally, neither ringing nor distortion are considered desirable, but some people prefer them, because it sounds louder and fuller.
