Usually only larger (dynamic) grain might get removed, but best simply test it out. 
There are some folks over at doom9 who are looking for ways to get more control over what gets removed when those functions are used in Avisynth, but to my knowledge none of these have been ported to Vapoursynth.
Side note: Sometimes it can help to restrict those functions through a mask. (Hybrid has some basic masking support, which probably will be extended in upcoming versions. Dev version already can to a bit more than the last release. To enable the masking controls enable Filtering->Vapoursynth->Misc->UI->Show 'Masked'-controls)
