I've seen this argument repeated ad nauseum over the past 15-20 years. I think it depends on what you want.
Yes to some having consistent elements of UI make some users feel very happy about using your software. Most probably won't be able to articulate why, they'll just feel a bit happier.
I don't think there's an absolute in this discussion though. The web has proven that people value having access to more capability more highly than how well every aspect of that capability works. You could view the lack of integration as a weakness of the web, but for me it reads as flexibility/empowerment for the developer. It's possible to view developer empowerment as a negative, but in the case of the web it's enabled it to tackle some interesting use cases that you might miss if you stick to the rules too zealously.
BTW, I think it's possible to build crappy UI natively too. It's a mindset thing. The web isn't native on any platform yet there are some web apps with great UI. There are also some non-native client apps (like Chrome) that I think (admitting my bias in Chrome's case) do a pretty good job.
