Seat guru says their 737 Max8 planes have no TV, no power at the seat. Southwest has this.

"Free Entertainment Where available. Available only on WiFi-enabled aircraft. Limited-time offer.
We've got something for everyone. With a wide variety of new releases and long-time Customer favorites, all movies are viewable right in your browser - no downloads or sign-ups required!"

Does that mean you can stream their movies and shows and such on your personal device, but there's no screen on the seat in front of you?
