Thanks for your reply, yes by the sounds of it, it can sure be like rocket science haha. But fortunately that's not what's causing me issues, refresh rate matching is working as it should but I was more wondering about the non inky blacks I'm experiencing and was curious as to whether Kodi has problems playing back HDR content on Android (hence the grey transition screens etc) or whether it's something with my setup.

Cheers!
