Yes, but it is the specific type of distortion that matters. Can it be fixed in photoshop? Sometimes, but it depends on the quality of the distortion:

Pincushioning and Barrel distortion are easily corrected and are usually corrected. Compression and perspective distortion caused by focal length are different and cannot be as easily adapted in post processing. Now I'm not familiar with DxO, so I'm not sure of it's capabilities, but I still think it would be difficult to change the relative sizes of background items based on the focal length of the lens, though I haven't tried so it might be easier than I think.
