Well I do not have framerate nor color issue on NG anymore . Playback is smooth and tonemapping is cool. But all i have to do is change hdmi format quite often enhanced to standard which is more stable. Doing this shake the HDCP communication. which gives good picture quality. Main problem is HDCP or you can say handshake issue. I can not find if CE supports 2.2 hdcp . But the main culprit is that so far. Clearing cache of tv or changing HDMI format is temporary fix. I am sure you are facing this issue. People are right there is no framerate issue. HDCP bad communication remove the High definition efficiency from the playback content causing stuttering /framerate issue either bad or wrong color . To be honest. This issue gave me so much headache.
