I've thought about this before when I revisited fantasy after years of being in the CS domain which helped me abhor ornate writing. I definitely think there is such thing as TOO ornate but dead-simple language also feels bad. It feels wrong to just say its an exception with fantasy - simplicity is good because it conveys the same thing more clearly and with less effort. I would think that transcends all domains. Still not sure how I feel about this. I guess there is a baseline non-styled language that is all about communicating raw info and then there is style that can be applied to writing which makes it feel more natural in different domains.
Having said all this, I actually do like your example more.
