Correct. TLK is a "FOSS TrustZone software stack" and not necessarily called a TEE (though it does implement a TEE.) The distinction might seem academic, but is useful to note: TEE may seem to indicate implementing a specific set of APIs (e.g. those proposed by the www.globalplatform.org), whereas "TrustZone software stack" is meant to indicate that one could have a wrapper to implement a GP TEE, or may choose to have a software TPM instead, or both (or even another runtime altogether) within the carveout on the underlying core (the so-called "Secure World".) I've presented TLK in a couple of events and am happy to respond if there's interest.
