Well, if I save as JPEG in Photoshop, my JPEG image ends up as a 4368 x 2912 pixel image.
With PM, it's just 2496 x 1664 pixels.

Well, the 5D is a 12.8 megapixel camera, so the Photoshop size is correct. Could it be that they embed a smaller JPEG due to the enormous size of this sensor? What you need to do is find out what resolution JPEG canon embeds in its RAW files.
A quick look on the Canon website shows the following excerpt for the 5D, where it is apparent that the resolution you are seeing in PM extracts is exactly the "small" option. Maybe the RAW files embed "small" only. Could there be an option to ask the camera to embed "large"?
