I have also been testing the Intel EGL builds and have tried forcing RGB full and selecting “limited range 16-235” in Kodi. The issue with that is my display only accepts RGB limited inputs so the method doesn’t work correctly.

After extensive testing I still get the best results with these RPi builds. I was just curious if it was handled any differently than the generic Openelec builds.

It's purely handled by GPU harwdare, so there won't be any common behaviour compared to Intel EGL.
There should only be a single conversion. The YUV data from the video decoder gets converted/composited to RGB on-the-fly and output through HDMI.
There are different matrices used for the different YUV formats (e.g. 601/709 colourspaces) and the limited/full RGB output modes.

That is great to hear, once again the RPi just works. The YUY data is converted directly to RGB limited like it should and the fact that there is only a single conversion taking place explains the results I am getting. Thanks for the clarification.
