Dimmers with neutrals have different problems. We went so far as to have Crestron control a DMX dimmer, which controlled a Lutron Magnetic circuit dimmer. The output of the Lutron, 0 - 240V (overseas) went to 240V - 12V transformers with simple bridge power supplies and capacitors large enough to smooth some little bits of steps.
Even after manipulating the HELL out of the size of the lower dozen or so steps, those steps are still visible when dimming. At least the damn thing dims to zero!
This is not recommended because it means running all the LEDs off of a local brute-force DC supply. Our walls had enough space for JBL 18" subs, so the power supply was no problem, but in general? Too hard.

A good answer is easier with a clear question giving the make and model of everything.
