In DX11L, DX11, and DX12, the only four available settings that I see in my game client are the ones outlined in the guide, and it's been this way since MSAA was re-implemented into the game client back in WoD. The only time I have seen non-matching color/depth levels was back in the WoD 6.1 beta client, which were removed when it went live. So, unless you have a special game client, then those settings should not be exposed (or even available), but even if they were, then non-matching color/depth levels should not be used, because, from what I've been told, they are either a waste of time or could be detrimental to the overall image quality.
This is what the retail (and beta) game clients show as available settings, still today.
