My impression is that the ACES tonemapper is designed to make it so the image resembles that taken by film, and so the ‘incorrect’ appearance of film is the desired appearance of ACES. It’s a photorealistic tonemapper, not a realistic tonemapper.
Unfortunately, this seems to come at the sacrifice of SRGB. Rendering in the tonemapper won’t use the full SRGB gamut… [0,0,1] raw is drawn on screen as [3,0,225], and I’m fairly sure you can’t get it any more blue than that, at least without an HDR screen.
