That's a great comparison video.
I wonder if s_Exlogo's settings were correct. As I indicated earlier, I've done a lot of logo removal using Delogo, and you can set it so its "inpainting" is done primarily from pixels above and below the logo, which is what I see in the s_Exlogo example.
Your function does a good job, but it does look similar to what I get with Delogo. If you have a version of the original, I'd be happy to create a demo of what can be done with that, and see how it compares to yours.
