What is it about dun, exactly, that's got you confused? It's a modification gene that generally lightly dilutes the base coat color, gives the horse darker shaded points (legs, ears, sometimes mane and tail), but the most telling signs of dun is a very prominent and dark dorsal stripe, accompanied by a bar on the shoulders, often, there is also zebra striping on the legs, and sometimes there is also markings on the forehead.
Dun is dominant, so if the horse carries a single gene for it (heterozygous), then they will be colored as a dun. Heterozygous has a 50% chance of throwing a dun foal, homozygous will throw a dun foal every time, regardless of what they are bred to.
Yes, both dam and foal appear to be a bay dun...and very attractive as well.
Always remember that feeling of looking at a big, open country over the ears of a good horse, seeing a new trail unwind ahead of you, and that ever-spectacular view from the top of the ridge!!! Follow my training blog: http://robertsontraining.blogspot.com/
