Just got myself an LG C4 42" ! Help needed with calibrating for PS5.

Basically title. Got the C4 for 97k INR. Currently playing cyberpunk, sifu and gow ragnarok. I think it needs calibration since I can see some blacks being washed out in cyberpunk. I tried setting the fine tune black to negative value, but it reduces the details in the dark area. Anything else I can try?
