It's a weird one. 60hz is pretty low refresh rate. Definitely not a gaming monitor. But it's resolution is quite high. At this resolution, I think there's only one other monitor, the LG Ultra Fine 5k is which is like only $200 cheaper. I think for people that care about resolution/pixel density, this monitor has basically zero competition? There's plenty of lower resolution monitors with higher refresh rates.
I think you overestimate the popularity of refresh rates over 60hz.
The banwidth for 4k at 60hz is only now becoming mainstream.
