I’ve found the same to be true. I can’t tell the differences between the picture quality of either output. And I don’t use it, because I’m using one less input now. I thought there would be an improvement, but no.I have wii2hdmi on my hdmi television, honestly I couldn't see any difference at all compared to the component cables, so I ended up not using it. I expect the display will be even worse in 4K screen, unless your TV has some magical anti aliasing.
