Film simulations only affect the jpegs, not the raw files. However, in the data of the raw file Fuji also stores which film simulation is used (if any). SilkyPix and CaptureOne use that information to display the raw image as per the selected film simulation setting. You can easily switch that off (In C1: Base Characteristics -> Curve). When it is in 'auto' it will pick up the film simulation you've used in the camera. When you put it in 'linear response' it is the flat raw file without film simulation.

The film simulation is most certainly reversible when shooting RAW.

I can't comment on SilkyPIX, as I would never even bother with that. Most likely SilkyPIX does allow you to change things, it's just buried in that awful UI.

I'd suggest trying Capture One Express for Fuji, it's free and supports film simulations on the X-T2, and will also let you change the film simulation at will (and turn them off and use the default C1 colour profiles as well).

Of course we will know the content of the update only when it will be released.
 
Since it hasn’t been introduced and anticipated with a great deal of leaks or rumors ( as we saw with the great AF revolution which didn’t really happen) about its content I am guessing that this is strictly a necessary technical update.
 
I am not holding my breath or stay up late to wait for it. I might even decide not to install it at all if it turns out that the mountain has given birth to a mouse.
