This Blofeld is authentic to Fleming's novels because he is Polish and realizes the importance of information and also to the Connery films because:
he presides at a SPECTRE meeting with his face in shadow;
the meeting pauses and everyone stands when he enters;
he acquires a disfiguring facial scar across one eye;
in an impressive SPECTRE headquarters, he addresses Bond from off-stage before entering to meet him in person - like Doctor No who, in the films, was also a SPECTRE operative.
Addendum, 18 November 2015: The octopus rings are also authentic to the Connery films.
