If the photo was taken soon after install, there would be almost no gap. As the PT boards dry out they shrink in width providing a drainage gap.
After out new PT decking sat over winter the gaps are perfect. Also we then applied solid stain both for looks and for protection. PT decking needs to be sealed in some way or over the years cracks will form. And then freezing will enlarge to cracks. The clear slap on sealer will work as well as stain.
