Hmm, I did not find this at all. For me, GYBR and Captain Fantastic are like night and day. I found Captain Fantastic to sound incredibly lush and warm compared to GYBR, which is exceptionally bright and harsh (but still an excellent surround-sound title).
I listened to parts of Captain Fantastic loud and parts of it not-so-loud. I did not find this to affect my perception of the level of "brightness".
