I’m not sure.  Given the complexity, it’s probably neither a strict superset or subset; it’s also fairly likely that the outermost DSCP is returned from a tunnelled IP scenario.  ISTR that tunnels are supposed to copy the TOS byte on entry and the ECN field on exit, though there are almost certainly tunnel implementations which don’t do that.
