it seems to my old memory that while on an IFR clearance, in a radar environment, point outs of non IFR traffic, or non conflicting IFR traffic will not happen...UNLESS it is a jet.
I recall that JETs receive slightly better service due to their higher speeds.
ALSO, if you are IFR (not necessarily IMC) and do get a traffic advisory, you will NOT get a vector away from VFR traffic unless you request it!!!!
I can't find my books right now to verify this ,but I encourage you to check aim and radar services/atc services.
