why is urp with nearest-neighbour so bad as compared to point filtering on a render texture

[echo sinew]

pixelization is much better on render texture than on renderscale lower than 1 to get pixelization

The right image is the one with the render texture

how could i get this same effect in urp render feature

[quartz dagger]

So the second image result is "better" in this case?
The difference to me seems to be the mip map level
Not sure of the reason but I assume Render Scale purposefully applies a negative mip map bias to prevent blurring
