I haven't tested, but I find that very unlikely.

The effect of the database setting ANSI_NULLS when it's ON is that it forces
the SET option ANSI_NULLS to be in the ON position, even though the process
has it OFF. If the database setting is OFF, it has no effect, but the
setting of the process determines.

And to make it even messier, when you run a stored procedure, what counts is
the setting when the procedure was saved.

As far as I know, ANSI_NULLS has no effect on the interpretation of NUL
characters. ANSI_NULLS determines how things like "IF @x = NULL" works.
