All of the SS appliances I saw while shopping for mine had the same finishes. The thing you want to look at is the handles. If they are very different, that would look odd. I went with all LG for that reason, instead of mixing brands, although I did get a KitchenAid dishwasher because they have a flat front model. I forget now what Samsung handles look like, but most manufacturers make a distinctive handle for that reason: to make you buy the whole matching suite.
