@cddt are you referring to the Mexico / SA match?

Looks a bit soft in my browser, but I've got a 4k screen.

Checking the streams there are quite a broad range, up-to 1080

○ Video  --vid=1              (h264 416x234 25 fps 350 kbps) [default]
○ Video  --vid=2              (h264 640x360 25 fps 800 kbps) [default]
○ Video  --vid=3              (h264 768x432 25 fps 1200 kbps) [default]
○ Video  --vid=4              (h264 1024x576 25 fps 1800 kbps) [default]
○ Video  --vid=5              (h264 1280x720 25 fps 2400 kbps) [default]
● Video  --vid=6              (h264 1920x1080 25 fps 4000 kbps) [default]
○ Audio  --aid=1  --alang=en  (aac 2ch 48000 Hz 96 kbps) [default]
● Audio  --aid=2  --alang=en  (aac 2ch 48000 Hz 128 kbps) [default]

If I select "Low quality" it looks a bit blocky rather than soft. Do you have the video quality selector in your browser?
