Cutscenes and tonics

Say you use an Everlasting Koss tonic. Will you still appear as Koss in a cutscene? So would Kormir be speaking to two Kosses in the first NF mission?

Wiki notes "Some game cinematics will wear off the 6th year birthday everlasting tonics effects." As well, "The only tonics that can be used in explorable areas are the Birthday, Henchman, Transmogrifier, Yuletide, and Zaishen varieties."

from my own experience, it depends on the mission, a few factions missions ive done have still had my zenmai on, whilst many of the eotn havent.
