Microtransaction Consistency

Seeing the Black & White MTXs on sale, I was checking them out and noticed something odd.

The black microtransactions have preview videos, while the white ones have screenshots.

Not something game-breaking, but could you please address this inconsistency towards these MTXs and maybe others that may be affected?

Lacking a "preview" option in game, It makes it all the more difficult to purchase MTX that would be matching with the rest of a set-up.
