from changes in colour timing to stuff like DNR and edge enhancement
I feel like DNR is this generation’s Pan & Scan.
Consumers are annoyed at the black bars and less image? Make it fill the screen.
Consumers don’t like how dirty the image looks? Digitally clean it.
The unfortunate truth is that the majority of consumers don’t care about having the truest master of the original version of the film, but rather what looks the “best”, even if it’s monumentally worse in doing so.
This is why I like DVD so much still to this day.
Nothing had to be re-created as you say.
Are we talking about modifications from the original DCP to home media? Because I can name plenty of DVDs that suffered similar issues plaguing BDs, like DNR. Prime example given the website; The Phantom Menace.
