Independence Day was re-released to Blu-ray only weeks prior to the UHD version's debut. Fox's 1080p presentation really nailed down the image quality. It was practically perfect, leaving precious little room to complain or, seemingly, improve. While the 2160p UHD is more a refinement of an already excellent image rather than a total reworking, the results are clearly very strong.
It's the direct A-B comparisons where things begin to get more interesting. The UHD is certainly more refined, yielding finer, if not only extremely so, details. Take a look at the President in bed around the 5:20 mark. Skin texturing is more apparent on the UHD; the Blu-ray lacks the finesse and finer points of definition on the face, favoring a markedly smoother appearance.
