2018 Tesla Model S - Premium vs. Textile differences?

[superm1]

What are the differences with "Premium Interior" for a 2018 Tesla aside from the leather seats? Are there leathers in other areas that are added, and is the headliner/dash the same?

Are there any lighting differences (like door handles) and can I retrofit the differences?

Premium interior has a better sound system, heated steering wheel, wipers, and back seats, and the hepa air filter. No changes to the headliner or dash, lighting is the same as far as I know. Keep in mind that the "textile" seats still have a lot of leather on them.

I have ‘18 with textile. Wish they were still offered. Looks great, super grippy when cornering, easy to clean. Overall better than leather!
