No, it isn't. Just cause it wears the title of Fallout does not make it a Fallout game. Remember that The Burned Game also wears the Fallout title.
Yes, there is such a thing as a proper Fallout game. It's called Fallout 1. Fallout 1 'is' Fallout. End of story. Any game that comes afterwards is never going to be 100% Fallout but it is about being as close to it as possible while still moving forward. Fallout 3 and 4 has moved so far away from what Fallout 1 was that they are not proper Fallout games. Yes, what makes a Fallout game a Fallout game will vary depending on who you ask. it does not mean that they are right though. Just cause Bethesda owns the series does not mean that they get to dictate what Fallout is. Only Fallout 1 and the original developers' vision and design goals get to dictate that. Question is, does Bethesda follow it? Here's a spoiler for ya: They don't.
And yes, I am from "the NMA crowd", why does that matter?
Bethesda didn't do anything to 'me', but they did something to a series I loved.
You're looking really black today!

That means you're a colossal hypocrite.
