I've used the same model but had a terrible experience. The ghosting was far worse than similar monitors I've used. The colors were also below average for that class of monitor.
And HDR???? Brother if you call overblown contrast and brightness a good experience, that's all the more reason we...
I've personally had terrible experience with ease. And even for ease, models with such specs for under 50k(with delivery even) are impossibly rare.
But no point in arguing with someone being adamant. Either that or this is just lowballing.
40-70k for an IPS 1440p high refresh display is terribly hard rn without some caveat. Especially in the condition required. I recommend you to try VA panels. IPS is definitely much better but the price goes up a lot.
