The Xscope mirror, a free tool works without needing VNC but you need a paid companion app on the Mac to send the data.
I prefer to use screens on the iPad. VNC is the way that OS X sends it's video remotely to another display. If you don't use it, someone else needs to re-write that entire stack and it works very well for local networks.
As for why the app I recommend, it has an observe mode and seems to scale the screen much better than the Xscope app since it is designed primarily for designing, not mirroring. The same program works on iPad, iPod, iPhone of all sizes and retina or not displays. It is very fast and has an observe only mode so that you don't accidentally send touch events.
If you do decide to use it on the go for remote access, there is a free location app (similar to how Back to My Mac works) and works over ssh tunnels if you prefer more security than speed. It has great soft keyboard support and of course works with Linux and Windows as well. There is nothing I can say bad about it in terms of missing features os bugs or design.
It's a quality piece of software all around.
If you really must avoid VNC, there is another option. The Xscope app for software designers has a free companion app that runs on the iPad and will mirror your screen. It's more designed for counting pixels and looking at mockups you design on the Mac for eventual use on the iPad, but you can use it as a mirroring solution. It lacks any input from the iPad and simply sends the screen from the Mac to iOS.
It also is very high quality software - and is well designed, all around and fast.
This is for sure an iPad Air 2, correct? It should have TouchID (a fingerprint sensor) on the front.
To verify the model, go to the settings app, General, About:
- Model MH2P2LL/A is an iPad Air 2

TL;DR;
It depends on the app.
More explanation:
Many apps that look fine on all iPhones and iPads are basically the same app. They are written that way to work on all resolutions. (It's a good programming practice not to assume anything about screen resolution of the device the program is run. It's not always possible though).
However, there is the possibility that some apps don't look good on iPad Pro because developers haven't tested their apps on it. For example, in a game, you may view more of the field.
