Is VMAF70 at 576p the same as VMAF70 at 1080p in visual quality?

Yes. If you get the same score using the same model, it means both outputs have the same perceptual quality. In this case, based on the HD model’s definition, your 1080p output looks the same as your 576p output when seen from a 1080p screen at a distance of 3 times the screen’s height.
