The garage i purchased my car from had a 'Professional' come in to touch-up a couple of spots on the standard finish Satin Speedlines on mine. Effort he made wasn't great. So i had a go myself. Exactly the same result.
Unless its exactly the right paint; and absorbs / reflects exactly the same amount of light - you'll always see the spots contrasting IMO.
I went gloss soon after. With the diffuser, mirrors, bumper etc being gloss anyway - the reasoning behind the Satin wheels did and still confuses me !
