Optimizing Zidoo Z9X settings on LG OLED CX

Hi, I’m trying to set setting well for my tv and I need your help:

if I reproduce local file usb plugged with the tv images look a little brighter and satured (same oled light and video settings and video mode obviously) and when I reproduce video test like this () with tv I can see little black bars for all the lines…with z9x no: I can just see alterning black bars from “235” and to the left….. It should be better to see alterning black bar for all the lines or is better like zidoo does?

These are my settings (taken from Markswift2003 threads, thanks for the suggestions)…please suggest me how to set better for my hardware, maybe I did something wrong…thanks..
