isCollected issue

[Lombra]

"Visual" ID is the same as "appearance" ID is the same as "visual appearance" ID. It's a bit confusing how they use all these variants interchangibly. The appearance ID essentially refers to the item model and texture, while a source ID refers to a specific item.

You need the source ID:

local visualID, sourceID = C_TransmogCollection.GetItemInfo(itemID)

Thanks a lot - worked!
Edit:

if isCollected == false then

Shows all items (plate, cloth, leather ..), I read that someone said it would only show items you could actually unlock on that character which is false. Can't find any good methods/APIs so I'm wondering if anyone got suggestions on how to check if the item can actually can be unlocked by the character you are using?
