The quickest resolution of your problem will be if it is possible to send us a small application reproducing your scenario. It is very important how you merge the needed dictionaries - in code or not - and their order also.
If this is not possible, please let me know:
- which is the version of telerik assemblies that you use?
- which is the theme that you apply?
Despite that I have checked our styles for the MS Checkbox and it seems that it should work as expected in all four themes with dynamic colors - Windows8, Windows8Touch, Office2013 and VisualStudio2013. Since you said that runtime it does not apply, but initially it works as expected, it seems to me that it is related to some specifics in your application. Also I am not sure which is the focus state in RadTabControl that does not change, because as checked locally such is not implemented at all. If sending a sample application is a difficult task, a screen-shot or video will help me a lot in giving you an adequate advice.
