Glad you found it.  I knew the description of it doing the same thing was wrong from experience, but didn't have the manual handy to double check exactly what the difference was.

# DaVinci Resolve: Difference between adjusting Y or YRGB

(Asked by: username_0 on 2017-10-03)

In DaVinci Resolve 14, some operations can be performed on all of the Y, R, G, B channels at the same time or only on one of them.

What is the difference between adjusting only Y, or adjusting all of YRGB? The effect looks the same.
