Open below file. The spreadsheet shows that the uv_map face corner attribute is correctly populated with data, and is being passed out to the group output socket. However when accessed via the shader editor, the data is not being read correctly (at all)

Works fine when you use the Set Material node on the output geometry. This is unrelated to attributes. Even without attributes the material in the shader editor does not affect the viewport.
The cube you generated in the node tree does not have any material, that's why you have to set it. Alternatively, you could overwrite the material in the material settings, but better just use the Set Material node.
