Not sure how I missed that.  I just did a side by side comparison of the 
ARRL CW spectral plots for both the K3 and the FTdx-5000, and there is 
certainly a difference.  30db down from the peak appears to be +/- 350 
Hz for the FTdx-5000, and about +/- 125 Hz for the K3 as best I could 
determine from expanded views of the plots.  60 db down (still probably 
about S2 for a S9+20 signal) appears to be about +/- 1.35 Khz for the 
FTdx-5000 and about +/- 350 Hz for the K3.

Here's a thought ... if everyone owned a Yaesu the company wouldn't have 
to worry about designing receivers with close-in BDR because nobody 
could operate that close to each other anyway.
