The darker blue redit 32nd century discovery phasers have the wrong sound fx. They should sound quite like, if not identical to the TOS phasers, as used by the Enterprise as well at the end of Disco S2.
If you listen closely in this clip you can hear Discovery's phasers sound different to the teal-green ones used by the rest of the Federation ships:

There's also a visual fx problem, when you use overload/fire-at-will the darker blue beams go green.
