I am not an expert - just an avid knife freak - but in my experience "Stainless" means "Stain Less" not "Stain Resistent". Eg. s35vn is relatively high quality stainless knife steel - that does not mean it ain't gonna pickup stains - all mine did... I suspect one of the differences between my knifes / Elons Cybertruck vs. your cookware is that your cookware is mirror polished while my knives and the cybertruck are sporting "satin finish" which looks quite esthetically first 5 mnts - but is quite inpractical...
