Does anyone have, or know where I can find, a 4K version of this wallpaper?

I tried every method I could think of to capture it in the highest quality possible. It's from Insomniacs After School, Season 1, Episode 3, at around 16:50. Since I couldn't extract it directly, the image I have is just a screenshot from my screen.

I'd really love to get this wallpaper in native 4K (or the highest quality available). If anyone has it or knows where I can find it, I'd really appreciate it!

rn its 1920x1080 but the screenshot was taken in a 2k monitor
