I was actually totally expecting a little higher based on what I know (HDR and local dimming is extremely complex -- they triple or quadruple the price in some certain cases for first-come displays). Hundreds of individually separately-modultable LEDs (with more complex optics) is much costlier than one single modulatable edgelight and a sheet-based lightguide.
Prices will probably will come down in time.
Then again, for some readers here, price is no object.
For the upcoming 4K144 locally dimmable displays, it is probably the first time in history that true local LED dimming comes to consumer gaming computer monitors. Finally!
Man, I remember when it cost $1250 in year 1993 for a high end 17" monitor when everyone was using 14".
