I compared two files using YUView (requires qt5):
https://github.com/IENT/YUView
I also tried to define colorimetry info harder:
bash-5.1$ /dev/shm/ffmpeg/ffmpeg -f lavfi -color_range 2 -color_primaries
bt709 -colorspace bt709 -color_trc bt709 -i yuvtestsrc -frames 1 -r 25
-vf format=rgba,scale,format=yuv444p,scale -color_range 2 -color_primaries
bt709 -colorspace bt709 -color_trc bt709 /dev/shm/yuv-mpeg-rgba-
yuv444p.y4m -debug log
but it does not change outcome
