Normally we do not discuss specific search terms here - but this area is a pretty hot topic, so I am making an exception.
I do think Google is very sensitive to both the "replica" and the "counterfeit" question. It is a hard job to police the businesses who violate trademark law for luxury goods. You're right, at the moment those searches look pretty clean.
I just checked [chanel bag], but thought the SERPs were fairly poor quality (searching in the UK)
2-4 of the sites on the first page were just keyword stuffed 'thin' affiliate sites (I say 'thin' since the keyword stuffing was the only real content they had), and a couple of others had no real content either.
I don't know what the SERPs were like previously though since it's not an area I would go into, but they didn't seem too clear when I checked it.
