So Wii U DOES upconvert?

[Mr Khan]

I saw way, way more jaggies when i was running the Wii U Transfer software (which works entirely in Wii mode) than i did playing Nintendoland, and didn't notice a difference in the Wii U side of the transfer (rendered from Wii U in Wii mode via HDMI) to the Wii side (rendered over Component, 480p)
