There are a huge amount of changes possible assuming no one played with either in photoshop and both are the same file. It is the colour profile the file was tagged with on upload. ICC profiles can make a huge change to colour, especially if the file is just tagged and not converted. Just tagging a incorrect profile can alter the contrast hue saturation and tonal range drastically. It looks to me however like it was helped in photoshop.

Welcome to the frustrating world of digital colour.
