Hello,
I wasn’t able to find anything on resolving the transition effect. However, I was able to get a workaround going with some scripting to slowly increase the brightness. Have provided the below if it is beneficial for you at all. Basically, it will turn on lights at a low setting and then slowly transition the bulbs to almost being at full brightness. Hope it helps. Thanks.
