This isn’t really a pilot like in the old days, but I’m guessing that first episode does conform to whatever look they decided on for the entire series. However, there’s still room to play within those first episode constraints - assuming it’s indicative of any - to make the show pop a bit more.

At the end of the day that’s my biggest gripe with The Mandalorian thus far - it didn’t get me excited for more, and Star Wars is something I’m on board with to quite an extent by default.
