Default setting is a downscale for webgl, i think. I went to project settings->quality and set the quality to max and it worked great!
Ah crap you are right, it's down-scaled to 80%, I thought it was using my PC URP preset, but it was using the mobile one. The mobile preset also had other issues like an extra post processing volume, no anti-aliasing, etc. Dang wish I could re-submit with it in it's full graphical fidelity glory RIP
