There are some 32" 6144x3456 monitors nowadays and they occasionally dip to the $800 range when on sale [1]. But for a more direct comparison, the Kuycon P20 looks very Apple-like, matches the 4.5K resolution of the iMac, and is $799 for its regular price [2].

Many people report poor colour and uniformity with the panels Kuycon use. Also just on the specs alone the brightness is dismal.
The P20 is a 28" display so is much lower pixel density than the iMac.
The Dell is only 450 nits, and the Kuycon site says the it costs $1050 delivered to the US with a stand ($950 if you BYO VESA stand).
Even using the sale prices, an iMac is still cheaper than a Mini with the Kuycon.
Never heard of this brand up until now. Design is indeed Apple-ish, are the panels any good?
I think they at least used to be literally the same panels (though potentially a downrated version with higher dead pixel tolerance etc)
