I think wesk05 or one of the other AMLogic guys knows about 23.976fps sync with Netflix as well on AMLogic SoC's.
The MINIX guys certainly know about this as they use the same AMLogic Frame Rate Automation Kernels (FRAK) as well. They even have the same sort of option to turn this on an off in Android as WeTek uses.

I think what couto27 is saying is there is no confirmation that it is indeed 23.976Hz and he is actually right, the output is not quite 23.976, it is actually 23.9758xx (I will have to check what the last two digits are. I don't seem to remember it). I had raised this issue with Minix and was informed that Amlogic CTO said it is a limitation of the Java layers in Android. In reality, this difference is highly unlikely to cause any noticeable stutter.

WeTeK has resorted to a different approach to enable automatic switching to 24p for DRM protected services like Netflix. Amlogic's method is to use FFmpeg to probe the AV stream, read the frame rate of the content and switch the output refresh rate. This doesn't work for DRM protected HD content because it is sent to a protected layer.
