Of course it's not the same picture. One was taken with an SDR camera, and the other was taken with an HDR camera standing next to the first camera. HDR is not simple post-processing that can be applied to an existing image. It has to be captured in the image from the start. Starting with the camera. And then it has to be continued through any post-processing, and finally displayed on a device that is capable of handling the HDR info.
I think it is somewhat akin to taking multiple captures of an image, each using different exposure settings, and then combining those images taking the best from each and coming up with a composite. Something like that, in basic terms.
p.s. - The above description is my understanding of the process as it was originally done with still photos. I believe the techniques to come up with an HDR output in video are implemented differently. For one, I believe the control information in an HDR video stream instructs the backlighting of the display device to change for different parts of the image. But just like in regular photography, if parts of the image are blown out to pure white, or so underexposed that they are pure black, no amount of processing is going to bring detail to areas that simply have none. Hence, you need a camera (still or video) that captures different parts of the image at different exposures. I don't think this can be done with one single capture, but I'm not an expert on the implementation. I just like the results!
