The back rings are also in sharp shadow that happens to mostly match the shape of the planet from that angle.

Re: Titan would possibly be a better location for humans to land first, and one of the benefits listed was that you could see Saturn's rings up close

Titan's hazy atmosphere may make viewing Saturn itself tricky. It's debated how much it's "fogged out" and how often there are partial clearings in the haze. But at least the atmosphere can protect one from Saturn's radiation.
