Lumen GI and Reflections feedback thread

Hi, i have recently been updating some projects from UE4 to UE5 and decided to give Lumen a try - to see how it works etc. One thing I have noticed when I create all my sequences is that they start black and fade in. Whilst this is often a useful option it is something i would normally do in post - is there a way to remove this feature/effect?
