There may be a little more of what the OP is looking for, when Larian fixes the camera angles for a critical hit kill by the player. Right now I can never see what's actually happening when that big D20 die appears on the screen, but I think it's intended to be a "kill cam" view like XCOM. Probably with an On/Off option setting in the final game.

I doubt it will be full Faerun Chainsaw Massacre level, but some of the current graphics are pretty grisly. Like what a dead body looks like after Shadowheart kills it with Guiding Bolt. Looks like it's been barbecued to a crisp.
