@chrism.conner parameter 3 and 4 are your ramp rate at the switch and over z-wave, and both are set to 10 seconds, so you should see slow changes and not immediate ones. Similarly, parameter 5 and 6 are your min and max, dim levels which look about right based on my experience with the large base version of the bulb. 12 and 13 are your default level, which should have the switch turn on at 3/4 brightness. Based on that, the switch appears to be configured for dimming appropriately.
You should try holding the up and down buttons on the switch while watching the level state value on your phone. You can verify that the switch is attempting to adjust the brightness level live that way. If that doesn’t work, you might also try resetting the min and max to 1 and 99 respectively, then telling the switch to go to a 1 brightness level through your phone. That should result in flickering if the switch is actually dimming and these bulbs behave like their larger cousins.
