The list shows what formats can convert to EXR and what formats can be converted from EXR. Most of all - it does not use OpenEXR python bindings (it`s a hell to setup them in Windows environment), it just utilizes oiiotool.exe from OpenImageIO suite The conversion also allows for the output image file to contain pixels of different data type to those Position, Resolution and Layer respectively and control the order of The format stores binary image data that can be either 32-bit integer, 16-bit or 32-bit floating point which can also be compressed via a lossy or non-lossy compression method.
