...and received today!
I can report that the white is white (ish - more of an 'off-white', really) and not silver. It has a debossed title on the front and debossed symbol on the back. Both the 4K and standard blu-ray discs have artwork, so not the plain blue blu-ray disc of the original release.
However, as expected, it is matte and not gloss like the Best Buy version. For me, though, that's the only thing that lets it down. But otherwise I do actually prefer it over the original 2D & 3D blu-ray release.
