Yeah, this isn't like e-mail headers where different hops in routing will insert additional information.
The TCR is a list that wireless carriers use to decide if they'll let a SMS message proceed or not.
I doubt the message itself indicates that it was weighed against the TCR list (it would require modifying the message).
