Use system settings for watch face

Hi, I’d like to suggest the following feature:
I’m using the Garmin Epix Pro, and set the watch face to red shift (in fact, green shift on the new beta firmware) from 10pm to 4:45am. The SaA lock screen only shows the clock in white. It would be great if the lock screen could take colour and brightness for the Garmin AMOLED devices from the system settings for sleep.
