There are several factors.

  1. In good light, the image is taken with much more light. At base ISO, FF sensors are capable of registering many more photons. This means less noise - smoother gradations, etc. Lower noise at base ISO is often downplayed but plays an important role.
  2. Less DOF when needed, of course.
  3. Sharper images at equivalent settings.
  4. Better optimized lenses. Smaller format lenses need to be severely corrected which hurts the OOF parts of the image. For the same light-gathering ability, the lens design must be more extreme. Unfortunately, sharpness over bokeh is becoming a tendency in the FF world but hopefully, not in the MF one.
  5. If you combine (1) to (4), you get a sharper subject in a smoother background, with smoother gradations, which makes the image "pop".

DR only weakly depends on the format, at least in the m43-FF range, depends on the manufacturer, and the extended DR may remain unused for a typical shot. Color filters and separation is somewhat dependent on the format but manufacturer dependent again. Canon's crop cameras are more "color blind" but Nikon's are not, AFAIK.
