Good point. I'm not an expert on image file formats either, but I can see how color accuracy could be important to people.
Currently, the uploaded image is stored in its original format. However, when downloading, the browser assigns a default .jpeg extension to the file. You can still manually save it with the correct extension to retain an identical version of the original image.
This isn't an ideal solution, but it's a temporary workaround until we implement a better approach. Unfortunately, browser options for controlling file extensions during download are quite limited, but we will find a way, cheers.
