$300 cheaper and 8 years old now, so likely can find used examples if you wanted. It's pretty clear that 5k / 218ppi just has no significant market appeal at this point outside of the Apple ecosystem. There were a few other 5k displays, but they've all packed up since (including LG, they don't make that 5k Ultrafine anymore afaict)
Although arguably since the LG comes with a height adjustable stand it's $700 cheaper than the Studio Display 27"
