An update
Thank you all for the advice, indeed when playing games in the dark room with HDR on is when the OLED leaves IPS in the dark this is just as expected from the OLED technology. The issue I had was that the IPS colours in desktop SDR mod are excellent already so the OLED improvement was minimal in that scenario
The panel I got as far as I can see/test is perfect, and this is in stark contrast with the tattered case it came in, well no one looks at the case in the loft anyway.
I know there are fans in the back I can not hear them, I game with headphones all the time and in my day-to-day office work can’t hear them over the normal case fans
All in all, I think I will keep the monitor, I have 3 years advance warranty from Dell in case of any problems
Good choice. I am not surprised though. When someone like Grim5 slags the monitor off for months on end and then ends up buying one and loving it, that says a lot
