I concur. Dark comb does not change the colour much, if at all. However, dark comb tends to be older brood comb and can definitely pickup that brood slum-gum type flavour. Not always, but sometimes it does. Just depends on how old the comb is. Some people like it, some do not.
This may be a little tricksy, confessional in nature. Early season nectar here is dandelion and willow. Stinky and strong by its own rite. I have some customers that crave DL and seek it out. Just by the way I operate that first batch of DL honey tends to come out of brood combs that have been pulled up in the stack to be cycled out. Thus enhancing, strengthening, accentuating the already bold and rich DL honey. Those customers love it even more. So I guess what I am saying is if you have customers that like dark bold flavoured honey, give them the brood comb honey. If you have others who like light and fine stuff, definitely do not. This is why it is important to keep your extraction batches tagged and separated.
