Like others said, it may or may not hurt yield. HOWEVER, looking at your pictures, you look a little dry there.  I had the same thing happen one year when it was dry.  Part of the field had dicamba damage and the other half had no damage (different sprayer).  The part with the dicamba damage took 2 weeks longer to canopy and I had a new crop of weeds come on, which were impossible to kill because of the hot weather.  Long story short, dicamba damaged beans yielded 9 bu. less.
