Pretty much title. Maybe Riot could make it so when you are looking at a variant of a given skin in your collection, that variant is the one that appears on the preview videos for vfx, animations, finishers etc.

I'm planning to buy the Reaver Vandal and Op as soon as they hit the shop, but can't decide whether I want to get the red variants or black variants and there's no convenient way to compare them except trying to find youtube videos. An in-game solution would be very welcome imo (:
