Being as I already own DXO PL I did upgrade my NIK version and added the Vue point app for free.
Be careful what you wish for or DXO might spirit off Color Efex and Silver efx as separate apps for more money Wasn’t Film pack and Vuepoint once part of the NIK Collection I don’t remember
ViewPoint was included in Nik 3, and even given the name Nik Perspective Efex. But it disappeared again by Nik 7. Similarly, PL Essentials was bundled with Nik for one release, then removed again. Being cynical, it looks like DxO throws in one of these when a new Nik release is otherwise weak.
