Your colleague is basically right. The PS4 Pro does not have an option to output a 2560x1440 resolution. Furthermore, you cannot benefit from the 144Hz. So in principle not optimal and basically an overkill.
PS: If you effectively only intend to use a PS4 Pro with a display, I recommend a 4K TV, which usually also support HDR.
