I think it will be showing as satisfied because 6 years has passed from when it was put on. However, whether it was a CCJ or not, you can still be chased for the money if you haven't paid. If it was a CCJ the liability remains indefinitely; if it was not then the creditor can no longer enforce it by taking you to Court if 6 years have passed with no payment or acknowledgement of the debt, but the debt does still exist.
I was under the impression that CCJs and defaults are removed entirely from the CRA records after 6 years, so it may be worth querying this with Experian.
