If I may - don’t think of FilmPack as an optional extra. It is actually already included in PhotoLab and just needs activating, just like ViewPoint.
What DxO have done is to provide a cut price “lite” version by allowing you to ignore certain features.
In fact, if you were to activate the 30 day free trial of FP, there’s a fair chance you would realise what you are missing, as it is not just about film emulations, but much more.
And, no, I don’t get any recompense from DxO for promoting it.
IMO, the Selective Tonality sliders are very poor and cause all sorts of side effects - see this post Selective Tone / Highlights too "broad" - #41 by Joanna as well as this one Visible Posterization in PL8, in Bokeh Areas - #22 by Joanna
