Bottom line

Neat Image 4.0 does not guess what noise looks like. It relies on a "noise profile," which is a mathematical snapshot of a specific camera sensor's flaws at a specific ISO setting.

Furthermore, its sophisticated high-frequency detail retention algorithm changed how photographers approached low-light shooting. It allowed professionals to confidently shoot at higher ISO levels, knowing the resulting noise could be cleanly managed in post-production without sacrificing image sharpness.
