Performance - Scenes vs RM Trigger + Picos

I’m using some custom engraved Picos to trigger some scenes in hubitat. When triggering these scenes via a Pico there is a slight delay. However, If I trigger the same lights/settings via a RM trigger its instant.. you wouldn’t know it wasn’t native lutron….

I’ve set the transition time in the scene to ‘0’ but is there something else that is happening with scenes that doesn’t happen with straight RM trigger = and actions rules? e.g. Is there some sort of built in ‘transition’ logic to smooth out the transition between scenes?
