The point about ANP is that the ANP of the Embraer is accurate enough to carry out GNSS only, RNAV and VNAV/LNAV approaches and it has done so for years which, obviously, means it meets the relevant RNP. You're unaware of this?

Still, the AT system is more intuitive and better in an operating environment than both the two types mentioned above.
