It doesn't sound any different at all. Unless of course people are clueless as to what is a canner/cutter versus an SS that might be good for 5 more calves.
You don't have to have a cow preg checked here. If you do, she may still go for slaughter. It is up to the buyer.
People can ask anything. Sometimes the ringman will ask the audience, "Is there anyone here who can speak for this cow?" Sometimes people do speak. Sometimes the just wave it off. Sometimes they bring up papers on registered animals.
If you don't know what you are doing, you could make a mistake. There or here.
