I suppose the answer is yes in the general. But does the correction sometimes make an image look worse? An example. One of the two images below is uncorrected. The other is corrected using the embedded lens correction as read by Lightroom. But the corrected one looks a bit more distorted to me? In particular, look at the motorcyclist's face and hair: What do you think? Ignore the different 'look' of the two different raw processors.
