How to get live wallpaper on IPhone 6?

Ok so here’s my problem. I have a perfectly good iPhone 6 that doesn’t let me set live wallpapers on my lock screen. I have an app and I save a photo from the app to set as my lock screen. I’ve looked at tutorials on YouTube and when they do it and instead of just still and perspective it has the option of like Live Photo. I’ve tried and tried to get a live lock screen but it just won’t let me. It might just be that I have an iPhone 6 and you can’t get it on this type of phone. If anyone can help please do so.
