I mean, yes, Berman/Braga era Trek has a fairly consistent style both visually and thematically because that's how they wanted it, but to privilege that style as "real" (or "proper", as you have it) requires considerable justification as yet not provided. Even from that era,
First Contact not only used a largely horror/action-movie style then unprecedented in Trek, but went far out of its way to cast doubt on the Federation's - and the TNG era's - doctrinaire self-congratulation about its "more evolved" ethical ideal, in the shape not only of Picard's desire to exact vengeance upon the Borg, but also of the lack of self-awareness that blinded him to it very nearly unto catastrophe. Was
First Contact therefore less "real"?
And if we're going to talk about ethics, we could do a lot worse than to talk about the Picard series's accidental but very real point that Picard's own moral absolutism and blind righteousness is as much of its time, as contingent, as any other ethic, and when taken out of a context where it's able to be effective, it does as much harm as any other, too. The point isn't explicitly made, because Kurtzman and Chabon are a couple of hacks just like Berman and Braga were, but it's easy to draw from the text on the basis of an almost trivial engagement - Picard's quixotism managing to ruin just about everyone it touches, and the writers having to fall back on a Bond-villain plot to try to make him come out looking good, is enough all by itself for that.
That's the kind of thing I mean when I talk about TNG showing its age. The remasters look pretty good, sure. But the Trek fandom has ever qualified their shows as especially worthy not for the quality of their visuals, but for that of their ideas. From that perspective, a lot of TNG, and of its era more generally, struggles today.
