It seems that the WiiU and Switch version of Zelda only differ in resolution and environmental sound effects.

As outlined by Nintendo in a statement to IGN, the Switch version will render in 900p on a TV, while its Wii U counterpart is only 720p.
The Switch version will also feature "higher-quality environmental sounds", Nintendo stated. "As a result, the sound of steps, water, grass, etc. are more realistic and enhance the game's Open-Air feel." Beyond that, the only differences are minimal, such as different button icons and the fact that only the Switch version will launch with Special and Master Editions containing bonus physical collectibles.
So no differences in detail or draw distance I guess. More stable 30fps.
Both versions will have a framerate of 30fps. That said, we noticed the Wii U version frequently struggled to hit that goal during its most recent E3 demo.
I guess the Switch isn't that more powerful than the WiiU if that's the only difference in docked mode. Can it even keep up with the WiiU undocked?
