Is turning supplemental logging in cdb means all pdbs have supplemental logging on?

Hi everyone,

1. in cdb, 
alter database add supplemental logging data.

does it means, all pdbs will inherit supplemental logging 
and do not have to go into a particular pdb to do this command again?


2. which data dictionary table will tell supplemental logging in pdb?
CHECKING V$database is only from CDB
select
   SUPPLEMENTAL_LOG_DATA_MIN,
   SUPPLEMENTAL_LOG_DATA_PK,
   SUPPLEMENTAL_LOG_DATA_UI
from
   v$database;  <--- ONLY for the cdb, what about pdb level?


SUPPLEME SUP SUP
-------- --- ---
YES      YES YES

Thanks
