Yes, oversampling will reduce blurriness but it will be there anyway. ClearType is there for the purpose.

Yet all that with the price of memory and CPU consumption - number of pixels to rasterize on 192 PPI monitor is four times of the one with "standard" 96 PPI.

It's not oversampling, it's native sampling. On high DPI displays browsers automatically apply a zoom to the page, so the canvas ends up being a smaller size that gets blown up. You have to detect this and create the canvas bigger to begin with to counteract this.
