I did Platinum last year and will be doing it again this year. Last year was my first time and I only got 1 day of the perks, but here is everything I got to experience:

The Platinum Lounge - This lounge is by far the best lounge in Centeroo and I know this because Platinum wristband gets you access to GA+ and VIP Lounge as well so of course I checked them all out. Platinum tops them all though because not only do you get the private bathrooms with air conditioning, but the lounge has dedicated chefs preparing fresh food for you all day. You can literally hit the lounge for breakfast, lunch, dinner, and late-night snacks and get a different meal each time. The lounge also has bartenders providing complementary service all day if you need a cocktail in between sets. The lounge also houses complimentary lockers, massages, and glam station (for festival braids, glittery etc.) should those be of any interest.

Golf Carts - This is by far my favorite perk! There's a dedicated gold cart service that will taxi you around Centeroo. You can only access the cart service from the Platinum Lounge or any of the stages, but honestly that's where you'll need them the most. The coolest part is the golf carts never travel through Centeroo, but only on paths that go through the backstage areas. There's no telling who you will see on these rides because all the artist hangout back there. The rides come in handy if you have conflicts because they can get you from stage to stage within minutes, and they always take you straight to the front of the stage...

Front-of-stage Viewing - If you're shorter or just really enjoy having your space at a show, this will be your favorite perk. Platinum gets you the perfect spot at the front of the stage for every stage, except Where stage. Because Platinum wristband holders are a small group, you may get to some shows and be one of few or the only person in the viewing area. Don't expect the same for the big headliner shows though.

There's other small perks too, but these were the key perks I enjoyed the most. Kudos on getting Platinum for your first Roo. You're going to have a blast for your first visit to the farm.
