Light.hue_activate_scene has delay

I have automations set-up to dim/brighten my lights in the home theatre when media from kodi starts, pauses, stops, etc. This all worked great and instantly using the old method of utilizing scenes of lights grouped in HA; however, I was reading how we can use the light.hue_activate_scene to utilize the hue hub’s built in scenes as this would change all the lights in the scene at the same time (there was a noticeable delay between the lights changing successively in the old method but the change still initiated instantly); the problem is that after changing my config to use the new method, there is a 2 to 7 second delay before the scene gets activated. This is frustrating because, although the lights now change all at the same time, there is an unacceptably long time before the change initiates.

I have tried changing the scan interval of hue to 2, 5, and 10 sec without joy. Kodi reports the state change almost instantly as proven by my old setup. Is there no perfect solution?
