Here are a comparative figure of the same plot, one exported with 512 px width, the other one with 2048 px (which has been resized back to 512 px in another image software for readability). Red curve has a thickness of 5 % of the frame, blue one 0.8 %.
You can see every lines are thinner in the 2048 px version. And you can't tell a thickness difference between red and blue curves. Take note antialiasing is turned on, with a supersample factor of 3.
if I change the values of antialiasing supersample factor for the same export width of 512 px, I get this:
The higher the supersample factor, the thinner the lines. This however is close to this issue: Edge line thickness when exporting PNG
