OpticFilm 8200i SE or Ai

Hello,
i am looking into buying a dedicated 35mm film scanner at the moment, because I am shooting mostly 35mm and am not satisfied with the results I get from my V550. I will settle for a Plustek OpticFilm 8200i but am unsure which version to get.

If I understand it correctly the Ai version comes with a calibration slide, which is not interesting to me since I only shoot negative film, and the ability to export images with 48 Bit color per channel, which would be important for NLP.

What are your thoughts on this and did I get the differences of the versions correctly?

Regards Felix
