After sometimes usage, last few days I decide to reset all the picture setting I set as I notice I actually make everything a bit too contrast and dark.

After reset everything to default for my EX600 TV, I find the default actually the best looking but just way too bright and I didn't know that it is absolutely easier to fix by just turning on the Ambient Sensor. With this turn on, it will auto adjust accordingly to environment light condition. Panasonic doing this part very well and it do out the output absolutely stunning.

Now I am using Normal for all SDR content and Dynamic for all HDR content. Both with ambient sensor on, color temperature to Warm 1 and also completely turn off the Adaptive Backlight Control and Intelligent Frame Creation.
