is it possible to extract 'LifeCycle Status' using emcli ( Oracle Enterprise Manager )
It seems that it's not possible, but, for the record, here's to get get the information via SQL.

SELECT CASE INSTR ( cm_target_name, '_' )
WHEN 0 THEN cm_target_name
    ELSE SUBSTR ( cm_target_name, 0, INSTR ( cm_target_name, '_') - 1 )
END database_name, property_value
FROM sysman.cm$em_tprops_ecm_view
WHERE cm_target_type = 'oracle_database'
AND property_name = 'orcl_gtp_lifecycle_status';
