I enhanced it myself the other week, pretty clear it's not real but very hot and a long one too.
I will upload it when I get chance in a couple days Edit - and in regards to the neon bull scene - unless someone can find a direct blu ray rip I can't get any extra detail that's worth it from clips online, I'm not that experienced with brightening clips up though.
Posting a link to a compressed 480p video when there's already some 1080p videos available won't be magically better.
It would actually be interesting to find some already clean 1080p high bit-rate footage and upscale it to 4K, those are the ones that'll get the best benefit.
We'll then be able to play a little bit with the lighting without losing the whole picture.
