My local Target store received another round of their Exclusive Black Series 6" Luke Skywalker (Jedi Master) on Ahch-To Island figures and while looking at this batch I noticed that the Hair on his head was a bit different then the previous ones I bought. At first I thought maybe the one I was looking at was just a one off factory error but found 2 more like this from this case.

In further investigation the one on the right (which I just found) looks like the prototype images released from Hasbro and the one on the left (bought a few weeks ago) has a better looking hairline and lower bangs that come down to his eyebrow.

Anyways both have the same date stamp, but assuming the one on the right was produced first since it looks like the prototype photos which can be viewed on Target.com.
