All I know is that I wish the Jailer still looked like this:
Now this is what I envision a real lord of Death to look like. Ancient, because Death is timeless, but also elegant, regal, because he is a God. It would make the Titan parallels even more obvious, as he looks like an evil Aman'thul.
Unless they recycle this old design for the Jailer's final form, or this "real" Jailer you're talking about.
