I am working on a trailer track with a composer in another country. To work together, we have to balance our templates. In the process of doing this I found that the top of the Marcato patch in CSB is just about the same dynamic as the top of the brass in Ark 1. Here's a comparison of the 3 Bass Trombones and 3 Horns in Ark1 to the equivalent instruments in CSB:

(the lowest Marcato dynamic is not the softest CSB can play, so I put an example of CSB's lowest Sustain dynamic at the end of the MP3).
Not a very musical test I admit!
IMO, no dynamic level higher than what Ark/CSB demonstrates here actually exists
Instead, in my observation, composers make the brass ensemble
larger to sound more massive (the 12 horn patch in Cinebrass or Century Brass, 9 horns in Ark1, 10 horns in Trailer Brass, 6 horns in Hollywood or Spitfire Symphonic or Caspian, etc are all good for this...) and they use some multiband plugins to really bring out the crispy highs from the melodic brass, a sort of artificial cuivre.
I'm really finicky about having proper dynamics in the libraries I use and NOT having to use CC11, and CSB has the same real, full dynamics I love in Hollywood Brass. IMO few developers since EastWest have really gone the 110% effort to capture the
full range of brass.
