All parts of a wheel interact. If a wheel is true at uneven spoke tension, then bringing ALL spokes to the same (high) tension will bring it out of true.
To keep/create an evenly tensioned and true wheel you might need to slacken the taut spokes as you tighten the slack spokes.

If you have no experience truing wheels, best to let the warranty cover it.
You don't want to take in a wheel that you have all out of whack because you tried unsuccessfully. It kind of makes for "hard feelings".
IF it were an old beater wheel, I'd have a somewhat different opinion.
