The latest version of the software is called PenAttention and offers settings that you can use to configure the way the software works. CursorAttention doesn't have the autodetect function like PenAttention does, but if you change the scaling of your desktop, then the color should be displayed correctly.
Go to Control Panel and use the Search field then type scaling and open the options windows. Adjust the scaling on the go and watch if the cursors calibrates itself.
