Samsung Day Cal/Night Cal setting.

[lukasz2]

Hello guise,
Recently I wanted to change few options in my QE49Q70R QLED TV. This is only 60Hz panel.
In my opinion the colours of this TV are .....inaccurate. The faces looks kinda reddish and grass look like a green field....
I lower te colour and disable contrast enhancements but the picture looks ....faint.

But my question is ......Can I put this options ON in SECRET MENU without harming TV?
Flickerless - I wanto to enable extra clear motion setting....
Blurr reduction - What is acutually doing this option . I want extra blurr reduction....
HDR Plus Support - Is this option add and extra HDR option in picture menu ? I have read that it tries to convert SDR content into HDR standard.

What other option is it worth to change to get better functions and picture?
Thank you.
Sorry for my language
