quick question on direct-path insert

Hi everyone, how may I confirm data is really loading as direct-path insert? I tried to load a table using direct path insert but looking at the plan used on v$sql it seems that I only have a regular insert, here is the plan:

select plan_table_output from table(dbms_xplan.display_cursor('3k35v36x1bbdg'));

PLAN_TABLE_OUTPUT

------------------------------------------------------------------------------------------------------------------------------------------------------

SQL_ID  3k35v36x1bbdg, child number 0

-------------------------------------

insert /*+ append */into target select * from source

Plan hash value: 2263300755

-------------------------------------------------------------------------------

| Id  | Operation          | Name     | Rows  | Bytes | Cost (%CPU)| Time     |

|   1 |  LOAD AS SELECT    |          |       |       |            |          |
