First of all I know next to nothing about MacOS. For your monitor, as it is hardware calibrated and 99% of AdobeRGB I would use AdobeRGB as monitor profil in dt. Now if the cairo port only support sRGB that's too bad, but at least dt and your monitor would agree on the profile to use. And cairo will do whatever he can to display the actual color (that is, either shrinking the color space to sRGB or keep AdobeRGB or whatever in between). If you do see a difference, it may be that cairo is not so broken or maybe only the soft profile in dt won't be properly used. But in your case you have an hardware calibrated monitor, so it may be a different story. Hope this helps!
