Let me know when I can buy the Apple TVI'm testing the firmware 001.001.233.012 and at the moment I have not faced the Dolby Vision bug. This does not mean that it isn't there anymore since @Tounsi98 does report he/she has still some issues with it. I know that this bug is a strange one. It can disappear for a while and suddenly it's back.
But at the moment I'm not having it with the Apple TV and a blu-ray player. The Apple TV is set back to have Dynamic Range and Match Frame Rate on. For now it seems to work...fingers crossed.
The audio is another story...it isn't any better! Philips OLED806 sound is buggy
