I would go so far as to say that unlevel horizons in a nature picture disqualify it from being true nature in the sense that water doesn't flow uphill. In general, unlevelness is unsettling and distracting to me. I need to level pictures hanging on a wall, potted plants in a yard, etc. I always use a level in construction projects. It could be a guy thing. But your concern is very real to me.
I can think of places in NV near Reno where the "horizon" slopes because the ground does then beyond rugged mountains. There is no horizontal horizon.
