Where? I've looked and there's nothing obvious - they may only become obvious when you actively take a screenshot and try to find them. And when you're playing it in the game, no, there aren't 'repeating patterns' in that stuff. They appear to have designed foliage in a way that avoids a quick copy and paste texture job, and added shaders and physics to the whole lot whilst making the next gen port.
This isn't a question of photorealism, either. You can go for a certain cartoony artstyle and fill it with insane amounts of different textures. You can see that one small cross section of a single road in GTA (about 10 metres by 10 meters or so) has about 50 different types of ground textures, not including debris, I can't help but think that attention to detail - that desire for excellence - that's what I paid for, and paid for again a second time. So yes, when I see that certain rock faces in the new Zelda are just completely flat with a texture stretched over it, and fuck all else, I think I'm within my rights to call that pretty sloppy - and the game world barren.
There was a moment in the Zelda video where they showed a field with plain grass, no rocks or flowers or plants or bushes or animals or debris or bugs, and with trees each spaced out about 20 metres away from each other. You know what Miyamoto-san called it, you know what he said it was?
A "densely wooded area".
