Yes, that is what I found too. More open top, and less mids. At the moment I'm still waiting for a FD3 neck pickup to arrive, so I have an FDV in the neck, and FD3 in middle and bridge. I'm still trying to convince myself to leave the FDV there for more variety, but it's just not what I'm in the mood for right now. I'll probably switch things around again in another 6 monthsListening through my iPhone speakers, it seems the FDVs have a more open top end.
Would be interesting to compare those samples by loudness-matching them
My collection will be 3 FD3Ns, 3 FD3s, 3 FDVs, and 2 SF2s. Collecting pickups is getting as bad as collecting pedals.
