Most (all?) new shower valves have an adjustment that limits how much hot water can mix into the output. How that is adjusted on this faucet, I do not know. But, if you take the handle and maybe the trim off, it may become evident. There'll be a screw, cam, lever, or something that you can adjust to increase the amount of hot. I've seen a couple of valves that had it set to max hot out of the box, yours apparantly is set to a much milder setting out of the box (or adjusted by the installer). Some people adjust them summer and winter to account for the colder incoming water temps. But if you adjust it now, you may find max it too warm in the summer.
All new shower valves are required to have anti-scald technology, so if you turn off the cold, it should actually stop the hot...I suppose a small trickle might still qualify. Be aware, though, that sometimes this will stick if you don't have both the hot and cold supplies on. Often, you can just tap it to get it free, but it gets worse sometimes as they get older and the seals get stiffer or they get mineral deposits on them.
