Regardless of whether or not the game has online features, there is a Daily Log on the Wii U that will show that you played BotW early. The log will also looklike \web, Mii Maker, Zelda. I wouldn't doubt that Nintendo collects this info to see what types of games are popukar.
So I think it is reasonable to suspect that Nintendo will know you are playing a pirated copy if they look. It is up to you to decide if you think Nintendo will crack down on piracy of their most anticipated title, most expensive title, and potential highest system seller in history....
IMO they have done more for less, but I understand the desire to try before you buy. It has a rough dev history - all gamepad features removed - evidence of fps problems - all clear idicators that the games exists for the switch and is exists on the wii u as the alternate patforn - not the primary
