Changing the pixel format from yuvj420p to yuvj444p of screen1.jpg with ffmpeg -hide_banner -i screen1.jpeg -pix_fmt yuvj444p screen1.yuvj444p.jpg, or changing format from jpg to png , then everything works okay.

The issue seems to stem from using kCGImageDestinationLossyCompressionQuality with 1.0 (lossless) in ImageIO. I've managed to workaround it locally by assigning the compression quality to a really high number (0.9999999, anything higher seems to get treated as lossless).
