Can't seem to apply image as finish to concave surface, convex face works only somewhat better

… but after the finish is applied “position” was just never available as an option on the domed disk.

Read this:

Can't find way to edit texture orientations

You’ll only get the Texture Position entry if the texture is applied to the faces inside the group or component AND you’ve only got one face highlighted. If you have the texture applied to the faces, turn on Hidden Geometry and check to see if your surfaces is divided into several smaller faces. Or share the .skp file so we can have a look.
