From vw.ca - the available packages for the Arteon:
Driver Assistance Package ($2,095)
Area View 360
Camera and/or distance sensor (driver assistance system)
Lane Assist
Park assist
R-Line Package (2,995)
20" Rosario alloy wheels 8J x 20
All-season tires 245/35 R20 95H
Aluminum door sills with "R-Line" logo
Black headliner
Interior décor: Silver Rise
R-Line leather heated multi-function steering wheel with paddle shifters
As expected, being an R-Line package, it only adds some overpriced cosmetic bits and nothing more. The steering wheel has an R logo on it and (useless) paddle shifters.
However, unlike lower VW offerings, this one is properly finished all around with higher grade materials and finishes.
