Here's a YT video that shows and describes the leather seating in the Limited. The reviewer refers to a cloth insert with the premium leather seats. Starts at the 7:30 mark. Hopefully it will wear well over time.
I ordered the Night Edition. On the RAM Night Edition link, the seating options are described as such:
"ALL-BLACK INTERIOR
Sink into leather-trimmed black bucket seats on Laramie®, Rebel® and Limited, go for deluxe black cloth bucket seats on Big Horn® or opt for 40/20/40 split cloth bench seating on Tradesman®. No matter which trim level you choose, this truck interior is dark to the core."
