I'd say you need to wait for a better example before making this type of comparison. There's a lot more that could be going on here to give a proper 1-1 comparison (dev-time, if it's complete, if this is somehow being streamed in "undocked" mode, etc.)
Look at something like Zelda and then look at this. This looks awful compared to Zelda, because they've probably spent a couple hours porting it to the system and/or it's incomplete.
I'd rather see a comparison on a game like Yooka Laylee, or Dark Souls (if and when that comes out). Hell, the small amounts we've seen of Skyrim on Switch (if that is what we've seen) looks lightyears better than this - there's no way DQ Heroes II is pushing what the Switch is capable of - no way.
