Some of the filter options are labeled as CN-100, E-7240, SP/200 and PV/100F.
They are types of film stock that the filter is supposed to emulate.
All digital cameras have some form of in camera processing (Picture Styles) in order to turn the RAW sensor data into JPGs. However these creative modes are generally quite limited (Portrait, Landscape, Black and White, Standard etc). The Fujifilm range of mirrorless digital cameras do have some film emulation Picture Styles) but for most cameras anything like that would need to be applied separately in post.
