Yeah, that's definitely the plan, for when beta launches we also wanna completely hide the creatures on the inventory list until you encounter one, if uncaptured, it'll show the image of it, name and serial number but remain gray. When captured, it'll show it in its colors, the highest rarity you own and how many you have.

Here's a preview of how the inventory list will look like:

So you can imagine them all listed down like this, however if you've never encountered one it'll not show the image and type border around the creature and type symbol at the far right, the orange border represents the rarity you own and the #8 is just the serial number of the creature, the last of the alpha starters.
