Samsung S90H Tandem panel don't show dark scenes correctly

Any fix for WOLED Samsungs displaying very dark scenes like I was using IPS panel?

There is zero nits pure black and bright scenes look great with good level of black but very dark scenes where I should struggle be able to see because its too dark look completely washed out with elevated black level.

I disabled all auto contrast stuff, black equalizers, AI and all. HDMi levels are correct.

Panel doesn't seem to be able to display anything darker than what already is its #010101 level which doesn't scale well with lowering brightness. If its 100 then its same level basically as brightness at 0. Rest levels are to scale more or less (note: there are some gradation issues at low brightness).

Any e.g. service trick to e.g. decimate panel luminance by reducing voltage to panel to make it darker to make it display darker levels as darker than what is this #010101 level? Or maybe a way to enable that diagonal line dithering like LG is I guess faking near-black gradation Tandem WOLEDs? I saw some people complaining about diagonal lines on Samsung WOLED so maybe there is setting in service menu to enable it... I literally don't need or care for this TV being super bright. It only need to be somewhat bright like CRT's were in the past.

Of course the solution here is to get QD-OLED as all WOLED panels are terrible at near-black but I use this TV (48S90H) as monitor and mostly in bright room anyways and text rendering on RGWB WOLED is better, it should burn-in less and most content looks nice. As IPS replacement its okay, bright content looks great and with tons of light in the room issue is not that severe... or more precisely I see its more like IPS at places but yeah, I wanted OLED quality and not IPS quality.
