I doubt it's esseriana, the winter growth is far shorter leaves for me and summer growth is pretty distinct for the species, but it doesn't quite look like my ehlersiae either....
Here's a photo of Pinguicula ehlersiae found through cpphotofinder. It looks close. I would recommend looking up Pinguicula esseriana and Pinguicula ehlersiae on CARNIVOROUS PLANT PHOTO FINDER to try to tell for yourself.
How much light is it getting? Joseph Clemens has a photo on this forum of an etiolated esseriana that looks like your plant.
You should definitely update this thread with the flower it appears you are about to get. Users will be able to offer much better help with ID that way. Also, if you have photos of the carnivorous growth that would also help very much with ID.
Neither photo is showing up now, but what I recall I think I can probably agree would fit for an etiolated ehlersiae
