I think what you’re interpreting as detail is artificial sharpening which has made some of the deeper pores on Ford’s face more pronounced. Zoom in really close and compare the two, there are more micro-contours in the grain pattern on the WOWOW. Look at his hat. In the WOWOW it looks like, well, felt. In the bluray it has taken on this ultra-smooth, plasticy look from the degraining. This is also visible if you look at the stubble on Ford’s face. This same smooth, plastic look appears there as well, compared to the more detailed WOWOW broadcast.
