It's not a gimmick. I know because since they swapped it out, the engine is much quieter, especially the valvetrain. Cold starts have no more chatter noise from the valvetrain that used to be there.
I'm pretty sure that even if Ester oil is not the most advanced stuff out there, Nissan would not have produced it if it did not do anything and wore your engine out faster.
