Remember how Tessa and the other humans at the gala were just shadows? Maybe that was because those events were shown through memories, through the eyes of a drone. Tessa now, in the present, has colour and a more defined form. The humans from the pilot in the exposition sequence are also not shadows. Eldritch J's human hand wasn't a shadow. The skeletons aren't shadows. We see all of that as is, without it being a POV or anything like that.
These solar eclipse shadows form due to the distance between the sun and the leaves on the trees. The distance and the proximity of the leaves to one another cause for a "lensing" type effect, making the eclipse shadow clearer to the human eye.
