When I set the screen resolution to the recommended 3840X2160, the extra large thumbnails are the same size as the large ones, just spaced out more. When I select a lower resolution, the sizes work properly. I have heard that this works for some people but I know of 4 other people who experience the same issue.
On my Windows 10 machine, at the same resolution, the extra large icons are around 3 times the size of large icons. I'm not sure why they are equal in size on your machine.
