That would apply to like a competitor, right? Another store that copies their motif to fool customers.

Has a court enforced trade dress with a mock version of a store within a game?

Would a reasonable person, seeing completely different letters actually think IKEA is sponsoring the game?

I would give IKEA almost a 0% chance of winning that case if both sides had equally sized pocketbooks. (see E.S.S. Entertainment v. Rock Star Videos (2008))
