Erm, he's not even standing in the same spot. Link is much further back on the WiiU, while on the switch he's standing on the rock in front of the church building. The only other difference is the sky reflection effect, old build or intentional no clue. Nintendo has stated that the only difference would be resolution and sound effects. (and perfromance likely)
Looks like I'll get it on the WiiU first, don't have a pre-order lined up.
