I opened .dng and .dng HDR (+3/-3 EV, HDR auto) files in PCDU 5. On both images there is the sky that looks overexposed. I dragged the exposure slider all to the left on both images but I didn't find any major differencies in DD of the sky between the HDR and non-HDR images. Am I doing something wrong here? If I had 3 images (0EV, +3EV and -3EV) and then manually merged them in photoshop then there would have been an unquestionable visible difference between the merged image and a single 0EV image.
Here are the screenshots of my manipulations in PCDU 5:
1. HDR
2. Non-HDR
And here is a link to the raw files and out of the camera jpegs (I shot RAW+) -

As it can be seen, when comparing ot of the camera jpegs, one can see a difference between the HDR and non-HDR images.
