RX100 high ISO NR comparison
My reaction is different from yours. The HDR image looks flat to me ... lacking contrast (check santa's body and the green bowl ... shadows are gone). The colours are also a little over the top for my liking, but I don't know what the original looked like.
Don't forget, some of these modes (such as HDR) are only good with fairly static subjects....
