Oh, no no. The nearest competitor I meant there was a monitor I would purchase, which was the Dell U2723QE (I think that's the model number anyway) which is a 4K HDR Monitor and rated quite highly for editors for accurate colours but using IPS Black panel instead of OLED. But that's at £630-£650 odd. Which after the discount code at Dell for the F version, means it's only ~£200 difference.
I wasn't certain if the IPS Black was good enough or not, although it is highly regarded by others, but if the difference is only around £200 that I can jump to QD OLED, I think I'd rather splash a little more for the QD OLED (as I've seen my old IPS vs the LG CX OLED).

OK, I just found a video that showed the IPS Black panel in action (using the LG CX Demo) and.... NOPE. Definitely going with the F then
