Comment:
͏ The input EXR seems to be of certain RGB colorspace ("gbrapf32le"?).
͏ The BT.709 etc. color handling applies only for YUV.
͏ Compare:
͏ `ffmpeg -v debug -hide_banner -nostdin -nostats -f lavfi -i
"sws_flags=+print_info; testsrc,scale=out_color_matrix=bt709" -vframes 1
-f null -`
͏ `ffmpeg -v debug -hide_banner -nostdin -nostats -f lavfi -i
"sws_flags=+print_info;
testsrc,scale=out_color_matrix=bt709,format=yuv420p" -vframes 1 -f null -`
͏ `ffmpeg -v debug -hide_banner -nostdin -nostats -f lavfi -i
"sws_flags=+print_info; testsrc2,scale=out_color_matrix=bt709" -vframes 1
-f null -`
͏ .

͏ "testsrc2" defaults "yuv420p".
