"Missing details" is the polishing job not the plating. Most run of the mill plating shops are not going to polish parts like this properly as they are not charging you enough to do it. The shops that do know how to polish parts like this are going to be very expensive. You get what you pay for.

When I need a part chromed I have the shop strip the chrome. Then I polish it myself. Then send it back for plating.

As for "too shiny"? Chrome is shiny. Un-polished nickel is not, but that's more for pre war bikes. Campy stuff shines.
