Sorry for my previous reply, I did not understand what your problem was.

It is indeed strange that the view DATABASE_PROPERTIES and its
underlying table SYS.PROPS$ does not reflect the change of NLS_SORT.

Maybe it is a bug in Oracle.
You should open a service request if you want to find out.

By the way, the command you give to change the database parameter
NLS_SORT is not correct. I get the error:

ORA-02096: specified initialization parameter is not modifiable with this
option

You can only modify it in the spfile.
