Spatial Video Downloads low resolution

Downloading spatial videos captured on iphone 15 pro from icloud on windows PC does not work properly.

The video downloaded from icloud is a flat low quality H264 MPEG 4 with no 3d effect even when "Download Unmodified Originals" has been selected.

Transferring via USB C cable directly works properly and transfers HEVC 3d spatial video.

I am new to iphone I only got it for spatial video so I may have done something wrong.
