I dont think it really looks outdated, don't see what more could be done TBH, change the background in settings is about all, but thats not a game changer for me, if I am in the settings I like it to be clutter free with little to distract me from the task I am trying to achieve, both iOS and ICS work well in this respect. If i am on an "app" page I just want to quickly identify the app I require, changing the tile pic would only cause unneeded confusion in the beginning for long term users IMHO. I use wallpapers to make my home screen pleasing to my eye, and have apps or widgets to give me information. I keep my screens clutter free whether I am using iOS or ICS, others think differently and have different priorities from a home screen.
