This is a recent Cedia post from Mike Garrett from the AVS Forum for NX5/7/9-RS1000/2000/3000 Owners:
Since it is Saturday and fewer people at the show, JVC did a private demo for Craig and me. We were able to watch different clips. We watched them three ways. Tone mapping off, auto tone mapping and dynamic tone mapping. We also paused certain scenes and viewed each of them the same way. There was quite a bit of difference. We paused and viewed one scene from the Meg, where the shark cage is lowered down into the water. With no tone mapping there is a large bright spot that is blown out and halos of discoloration around the cage. With auto tone mapping, the bright spot that was blown out was reduced and the halo and discoloration around the shark cage was smaller. With dynamic tone mapping almost all of the blown out bright spot was gone and same for the halo around the shark tank. Pictures would not show up on my iPhone, but Craig had a better camera with him and I think he was able to capture the differences. We took the pictures with the menu up, so that you could clearly see what tone mapping was used for each picture. We also watched clips from other movies. In all cases the dynamic tone mapping was superior. When we watched the demo the first time, we were surprised at how much flatter the image looked when using auto tone mapping vs dynamic tone mapping, but after doing the still shots, I can confirm that what people saw was not due to different settings. The dynamic tone mapping is a very definite improvement. Nice job JVC.
