My problem with this is the lighting doesn't make any sense. It seems like the lighting in CG scenes are completely inconsistent with how the composited real world actors are lit.
Then you have genie which is will smiths face pasted n a CG body which looks really weird cuz the lighting conditions of both look off, but they are directly connected. Genies body is overly specular while smiths face is not. There seem to be discontinuities in shadows and reflections between all elements of the scene.
Also smiths mocap looks wrong. It's like the finer details of his movements were filtered out giving a serious uncanny valley feel to it.
TL;DR: Lights in CG are different from real actor lighting.
In film there are always going to be some inconsistences due to staging of actors usually taking precedence over the rest of the elements in a given scene, but you're definitely right in your critique about the lighting.
Similarly, the lava scene was lacking in the emissive lighting department. It's really shocking how poorly constructed these scenes appear to be so far.
