The crispness is definitely there.

With the standard MG Zeta Gundam v2.0.

In photos the difference doesn't look all that dramatic.
The standard version has a lovely pastel tone even without any shine,
while the HD Color version has deeper, more vivid colors with a subtle reflective sheen.

The shield and wing sections are hard to tell apart at a glance, but the HD Color version does have a bit more of a glossy sheen to it.

Leg comparison.
The white molded color on the standard version has a slight jade/teal tint to it, whereas the HD Color version is a pure, clean white.

Waverider comparison.
It doesn't look like a huge difference in photos, but under lighting you can definitely see a clear difference in the reflective sheen.
