What else did they say in the landing clearance? ATC did not advertise the 5/5/5 and leave it at that. Conveniently, there's more to that transmission than you're talking about.
ATC is obligated to give you the RwyCC when one is available. Please remember that these RwyCC can be old and conditions change rapidly.
