After changing the parameter O7_DICTIONARY_ACCESSIBILITY to true, I can log in as SYS without (as sysdba) or (as sysoper)...

From sqlplus

SQL> show user
USER is "SYS"

At any later stage how am I to know that I have logged in not as SYSDBA???

It's recorded in sys.v$session_connect_info:

SQL> conn sys/oracle
Connected.
SQL> SELECT DISTINCT(authentication_type) FROM v$session_connect_info WHERE sid = USERENV('SID');

AUTHENTICATION_TYPE
--------------------------
DATABASE

SQL> conn / as sysdba
Connected.
SQL> /

AUTHENTICATION_TYPE
--------------------------
INTERNAL


PS: O7_DICTIONARY_ACCESSIBILITY should be set to FALSE for better security.

Never do that, this parameter MUST be set to FALSE.
