Yes it does cost and it DOES make a difference. You think radial aircraft engines that use chrome plated cylinders are gonna go with china chrome? Yeah, lets see how that works out. I've seen that kinda chrome up close first hand and it's a work of art!But it does get your car on TV and a ton of awards.
Stay away from Cheap China chrome. I paid more to get a good set of original MaMopar valve covers plated after I stripped, sanded, polished them than most would pay. quality Chrome cost. Sadly, I lost my source that plates thanks to the EPA! Same goes for cheap oil pans that are plated chromed. All junk.
