Let's go through step by step.
The Original file _MG_1982.jpg is a modified JPG file by 'Adobe Photoshop CC 2015.5 (Macintosh)' application. Doesn't matter, it was intentional or not, to make correct comparison the original JPG ( or RAW ) file needed. If you have the original file and it is too big to place here, reduce its size with a 'less intelligent' application, which certainly doesn't make more only merge pixels.
The next would be to import same image to DoP and select from the Preset list the 'No correction' by double click on. Finally, Export the result to JPG - any size, preferable same as the original JPG reduced; I recommend 960px horizontal - and add here to your message both. If you find any difference in tonality, it is the error of DoP. Of course, in the Export window leave the ICC profile Original and the EXIF details also allow to save.
