That's not correct. If you want the new Google launcher (with transparency, ok google, bigger icons, etc) then you also have to download and install the GEL apk after installing KitKat. Get it from How To Try The Google Experience Launcher With Translucent Bars And Google Now Once You Get Your KitKat Update [APK Download]. Just download it on your phone and install directly so it is a piece of cake to install. It is not available in the Play store. I installed it and it is really great. I have an N5 also but the N4 is essentially the same now with just a slightly smaller physical screen.If you flash the factory images obtained from Google using Fastboot then your all set, no need to do anything further.
