The post work happens on both renders and photographs, so it doesn't matter which method is used. The goal is typically to highlight all features that are visible in the shot, even though under typical lighting your eye would only be drawn to a subset of them at any given time. With elements like the band, they would try to match the typically perceived color. Metamerism suggests this isn't possible for every condition, and obviously the deep shadows here influence that. In that regard it is a judgement call on the part of whoever prepares it followed by whoever signs off on it. It should be close enough that you don't feel like they're different colors viewing on whatever display unless you compare them side by side. There are too many factors including screen brightness and various lighting conditions to make them identical side by side with every display under every lighting condition (again partly due to metamerism).
