Native 4K or Checkerboard "uprendered" 4k

What do you mean by "depends on the panel"?

I don't think a panel can get rid of the blurry picture by upscalling.

Nevertheless, I just checked again by not using AA. The 4k is crisp as it possibly can be. The upscalled 1080 image is still blurry. And obviously less details are being shown.

1080 upscaled no AA

That's a pretty bad upscale, can't you set it to quadrupling 1080p content? It should not lose brightness or color, just give you blocky 2x2 pixels. My 1080p tv does a much better job with Wii 480p content, and that's not even a straight doubling. Much sharper than that picture you linked.
Monitors have always been bad at upscaling though, hence I always to prefer to play in native res at the cost of frame rate and effects.

Ignore the brightness and color differences... it's the camera what makes it differ.

A monitor has really limited post processing features, probably none compared to a TV. So, there isn't much I can do about.

That's why you should always use native resolution on a monitor.
