Check if value changed from Default value

Just before I was trying to find out if the value from a column was changed from its default. The column is a VARCHAR2. Defaults (in ALL_TAB_COLUMNS) are in Data_Default, which is a LONG. Is there a way to do the comparison.

Something like

SELECT
        Moo
FROM
        Cow
WHERE

	Moo <> (SELECT
			Data_Default
		 FROM
			User_Tab_Columns
		 WHERE
			Table_Name = 'COW'
		     AND	Column_Name = 'MOO');
