That would be my guess as well.

Neither service animals nor the owners that are legally entitled to them are required to publicly brandish themselves as such. It's a matter for the passenger needing the accommodation and the company providing the conveyance; other people do not need to be privy, and I find it least intrusive and embarrassing to leave the matter at that.
