There are so few options for wallpaper. I've searched and can't find how to make and submit one. Can someone fill me in or link me? I'm a graphic designer, I should be able to make some more acceptable wallpapers for the community.
I don't think it's possible. At one time Roku was going to inform developers how to create themes (as they're called), but that never transpired. It could be that I just missed it since it wasn't something that interested me, but you can try to search for Roku theme development and see if you get anywhere.

I was searching for this and found the below on Roku's site. I haven't tried it yet but plan to. Hopefully this helps
To sendthephotos and videos toyourTV, all you need to do is downloadthe Rokumobile app for Android or iOS, select “Photos+” fromthemain menu and choose photos or videos. Seriously, it's that easy. You can evencreate ascreensaver foryourTV using pictures fromyourmobile device.Jun 14, 2019
That is not a way to make your own wallpaper that is a way to create a screensaver which is different what everyone is asking here and I am as well is there should be a way to use a photograph as a wallpaper background on your Roku for example I would just like a black screen I don’t know why nobody ever thought of this but it would be the most clearest way to see everything on your Roku home screen I use a black screen for example on my iPhone and it makes all the icons and everything clear as day why can’t I just have a simple black background for the Roku home screen how come nobody thought of this and why can I just do it myself????
