Filmmaker Mode

Recently bought a Lg Oled 65 B4 2LA and I've been trying out the different presets yet i can't seem to work out Fimmaker Mode. I have set it to auto detect and indeed it does on the tv apps suchas Amazon yet it doesn't through the exact same app and film on my XBSX. Also it doesn't seem to kick in on many other Blu Ray titles I've tried. I understand it can be i used on any onput so im a bit confused. Thanks for your help in advance.
