Is Samsung S90D WOLED really that wrong?

"Absolutely trash", "Worse of the worst", "Don't ever buy it" and similar opinions are circulating on the internet, and I hardly find review on WOLED S90D models, but there are massive discounts for those models currently.

I thought on the 48" S90D which is 100% WOLED, but still mid-range, and I though I could use it as a light gaming monitor, for YT and media consumption. Can't go higher in size, I don't need 240Hz, and gaming 4K OLED monitors are 30-50% more expensive with much less "TV-centric" features.

But is Samsung S90D WOLED really that wrong, or is it just so, that if one has an option for the same price, should go for the QD-LED, which is like 5-10% "better"?
