Not if you actually tried to achieve that in practice across all browsers and display configurations ;)
For instance Safari had for the longest time a hardwired (e.g. not fixable via CSS) linear filter applied when a WebGL canvas had to be upscaled. It's only been fixed last year or so.
Also unfiltered upscaling done breaks down when fractional scaling outside the browser happens, the result will generally look horrible and there is no good way to fix it. The only workaround is to make hide the scaling artifacts behind a filter, which then makes everything look blurry.
Browsers running on top of Wayland most likely still have all those issues.
The crisp text maybe it is unimpressive in the sense that is being used an graphic library targeted to games, so is using an homologous to pixel fonts. But it is not the norm.
I'm simply increasing awareness among the development community about the problems with text rasterization in applications and OS interfaces. I'm glad not to see blurry text.
