Here's my take on all this if anyone is interested.
From the original post I wonder if the neck was set too straight. An optimal setup should have relief from the first fret all the way to the last. If the truss rod is too tight (and the strings set too high) you'll have exactly the symptom you describe. Low action from the first fret to somewhere aroud the 12th and then it'll get higher. Typically, to correct this, you'd loosen the neck and lower the strings at the saddles. There is a sweet spot between neck relief and saddle height where everything should be as good as it can get. The guys at Lakland really know what they're doing and have been doing it for a long time so I'd be really surprised if the neck had some kind of issue. But, necks are made of wood and things can happen.
Regarding "fall away": When the neck is under tension there should be no apparrent fall away. The idea behind adding fall away is that it's done before the frets are installed to approximately guess where the neck will pull to under tension. Skilled builders develop a pretty good idea of how much of this they need over time and usually nail it in the finished product. We try to eliminate this guess work here in our shop by stressing the neck to simulate string tension when we sand the fingerboard true before installing the frets. Look up
Stew Mac's Erlewine Neck Jig to get a better idea of the concept.
You should not see fall away in a neck at pitch. If you do the truss rod is too tight, or there is a serious issue with the neck.
Hope that helps.
