It just isn't an option. I've seen those how-tos as well, but they don't apply to my particular TV. I go into settings, and there is no option to manipulate the existing apps that are available to me. The apps just have randomly become available over the years. When I first got the set, there was no Hulu or Disney+ app on the screen when I would press Contour on the remote, then navigate to the Apps. Then one day, those two were suddenly available. The remote that came with my TV has buttons for Netflix, Vudu and Youtube, so my guess is it's an agreement between Philips and streaming providers on what apps are available and when. I don't know, I find it odd but it is what it is.
I don't understand if we're talking about the TV and you reference pressing the Contour button. The TV has its own operating system and apps and Contour has its operating system and apps. Two different platforms. The Contour box wouldn't have anything to do with steaming an app on the TV set. You'll need to use the TV remote to navigate the TV apps.
