4k at 33" is awful too. 5k text is visibly better than 4k at 27".

I mean, sure, but you're basically saying "anything other than the absolute top-end displays are absolutely awful". 133 PPI is going to be higher pixel density than >99% of desktop monitors that people are actually using.

e.g. The Steam hardware survey only goes down to 0.23% usage, and doesn't have any >4K resolution listed.
