Comments FWIW:
1) Check belt tension:
If your belt tension is little to tight/loose, it can create some extra wobble on the blade during startup. Noticed thus on my contractor saw(s), and it was worse with Freud thin kerf blades as they seem to have thinner plate than most of my other blades.

2) Trust, but verify: Could be blade, or maybe arbor?
Measure the run-out of your arbor, then check run-out on couple different blades. You might have small variation that smooths out at full rpm?
On my cabinet saw, noticed have slight wobble during startup with thin kerf blades, but not with any full width 1/8 thick blades, or my dado stack. After about a dozen starts, they TK blade stopped making noise on new ZCI, so I never bothered to track down how my run-out was being created.
Note, Way back when TS arbors where trued line on machine. They ‘stone’ (or true) the arbor washer face flat/square to shaft with oil/water stone while running (blade removed). Forget where I saw the procedure documented, but sure Google can find it.

3) Have used LC ZCI for decades, and several different saw. Observed that sometimes the ZCI .vs actual cast iron table saw opening is not perfect. They usually fit well, but have seen inserts with room to move around. This will create the constant noise you mention.
I used a few layers of masking tape around what ever edge needed to take up any extra space. If the insert can slide front to back, or side to side; it will when saw starts and has highest amount of vibration happening. If need to take up a lot of space, can also drill and tap a small set screw into the side of insert.

As always, YMMV,
Best Luck.
