You order from a hatchery and you get hatchery quality.
It's like buying a puppy at the pet store. Just because they can give you papers that say it is a poodle doesn't mean it is a poodle, or even close to being a poodle. I don't think the hatcheries are nearly as bad as the puppy mills, but they pay the same attention to the standards of their breeding stock. Their criteria seems to be based upon whether they get chicks to ship, not upon comb type or leg color.
I've ordered hatchery ducks. They are fine, healthy and adorably cute. They will go into the freezer in a couple more weeks. They do not meet the SOP and I didn't expect them to, so I was not disappointed that they are all mis-marked and non-standard colors. That won't affect how they taste.
It's possible that they messed up your order and shipped you the wrong birds, so you can try contacting them. Just don't get your hopes up too high about what you will receive. It looks like you received healthy birds, so you got what everybody else gets.
I think Sebrights are lovely, but your best bet to get birds that look like Sebrights is to buy directly from a hobby breeder who pays attention to those things and where you can see what their stock looks like. You won't be allowed to go into the pens, but they will have photos and you can see their birds at the shows.
