I'm not sure this is a suitable question for here but is the new Chrome app for IOS just a UIWebView?
If so then would it be safe to assume that there shouldn't be any rendering differences between it and mobile Safari?
As of version 48, Chrome for iOS uses WKWebView, which is the same view used in Safari.

No, it is not just a UiWebView. Mike Pinkerton's post on chrome-team googlegroup:
Chrome for iOS has some pretty major technical restrictions imposed by the App Store, such as the requirement to use the built-in UIWebView for rendering, no V8, and a single-process model. As a result it’s been challenging to re-use critical Chromium infrastructure components. That said, there is a lot of code we do leverage, such as the network layer, the sync and bookmarks infrastructure, omnibox, metrics and crash reporting, and a growing portion of content.
The networking layer alone contains a lot of optimizations to enhance your browsing. Here's a quick overview: http://www.igvita.com/2012/06/04/chrome-networking-dns-prefetch-and-tcp-preconnect/
Yes, you're right... it uses the webkit rendering engine, with Chrome UI.
Ref. DaringFireball...
It’s not the Chrome rendering or JavaScript engines — the App Store rules forbid that. It’s the iOS system version of WebKit wrapped in Google’s own browser UI
