I'm not thinking of something that replicates the same phenomenom so exactly, just something that can aproximatedly do the same kind of blur.
you know, just some filter you can run pixelart trough so it spits something in 2X and it looks like Ironshin's TV shot.
BTW, I tried my hand at a CMYK ver.....

I reversed the brightness of the two brightest shades, but I think this version benefits more of the pallete this way
