Is there a way to identify snapshot PDB when mounted?

Hello Everyone, 
When I create snapshot pluggable database:

create pluggable database PDB2 from PDB snapshot copy file_name_convert=('/pdb/','/pdb2/');
Pluggable database created.

I cannot find any relevant information, that the created database was of snapshot type, when the PDB is in mounted state:

col name for a15
select con_id,name,open_mode, snapshot_parent_con_id from v$pdbs;

 CON_ID NAME OPEN_MODE SNAPSHOT_PARENT_CON_ID
---------- --------------- ---------- ----------------------
      2 PDB$SEED          READ ONLY
      4 PDB2              MOUNTED
      5 PDB1              READ ONLY

The column SNAPSHOT_PARENT_CON_ID gets populated only when you open the PDB:
