Nightmare on elm street 4 does look bad in the darker shots on capsaholic so with what I am talking about mixing Luma to get rid or black crush the main problem is you would have to conform the sources framing wise and these seem quite different looking at the Junkyard on Capsaholic and the girl in the room with the bike the DVD chops off the top of her head the Blu Ray is better framed but unless there is a source that has the shadow detail and in a similar framing to the Blu-ray then yes it is possible but like I said framing is an issue. But with all the versions of Star Wars and prints and alike it’s not really a problem per say to match the framing so much. In this instance it is a hurdle. (Not that my software can do it very well either!)

Ghostbusters does not seem to be a problem as the framing of the 2009 and new 4K master are pretty much the same and would probably just say get the 2009 Blu-ray potentially on that one. As it does not seem to suffer.

Nightmare on Elm Street 4 is potentially more obscure but if a source exists in the same framing without black crush yes it’s absolutely possible but even if you tried to conform the Blu-Ray to the DVD for NOES 4 you would potentially find more image at the top on Blu and more image at the bottom on DVD so it is a tricky one due to the framing and obscurity and lack of different releases.

Basically you can’t get the detail and the Luma as a whole unless a different release has a framing similar to the Blu ray on this one.

Potentially with the 4K ghostbusters Blu ray it has much more darker color information but your TV might be incapable of displaying it. This is a distinct possibility as mine won’t display HDR or anything… I have a normal old HD LCD monitor still.
