I tested this in XF (iOS 10 / iPhone 6). I don't see the problem. Can you re-test with this version?
Comment 3 Raphael 2016-09-30 19:27:59 UTC
Seems like with this new release the color is correct. 
However now the rounded border from frame is not working... 
See Example prints

How is in new pre-release
Comment 6 adrianknight89 2016-09-30 23:08:57 UTC
You're right. The latest pre-release does not have a corner radius. I'm not sure if this was intended or a regression bug.
Comment 7 adrianknight89 2016-10-01 00:02:47 UTC
I think this was intended behavior. Corner radius will probably be a platform specific implementation.  This PR (https://github.com/xamarin/Xamarin.Forms/pull/301) is where the corner radius stops working.
Comment 8 adrianknight89 2016-10-09 16:08:27 UTC
According to Samantha Houts, it was not intended behavior. So, corner radius might be a regression.
Comment 9 Samantha Houts [MSFT] 2016-12-06 18:33:52 UTC
The original report re: the color disparity appears to have been fixed, confirmed by Comment 3. The corner radius bug was reported as Bug 48509 and fixed in 2.3.3-SR1. 

Thank you!

An example is already attached.

Assigned to you because bug you were last to resolve bug before it was re-opened.
Comment 12 Cody Beyer (MSFT) 2017-06-19 21:40:53 UTC
Confirmed that the color disparity is back in Forms

revised sample

Consolidated sample comparing Frame, BoxView, and UIView along with existing UINavigationBar appearance. Color of Frame is slightly transparent by comparison.
Comment 14 Oliver Brown 2017-11-16 11:20:32 UTC
Is the frame color issue the same as this?


There is a (stalled) PR in progress:
