Am I Expecting Too Much?

I don't think you're being overly picky. Ours doesn't have wallpaper issues. I really don't understand why you aren't getting any resolution when you're under warranty though. We bought ours used and the dealer had a shop replace all the laminate flooring (removing some carpeting, reupholstered the chair and sofa and redid all the window treatments). Well the flooring started bubbling up a couple months after we bought it. The dealer had a warranty on the flooring (rig is out of warranty) and replaced it no questions asked. The replacement flooring FAR exceeds the first.
