Is there any research around that tests whether self-defined "night owls" are immune to the hormonal effects of sunrise and sundown (as visual stimuli)?

I once considered myself one, until I started actually rolling the blinds up in the mornings (Spanish blinds block all light) and staying away from blue light in the evenings. Being brought up in a cloudy, rainy town and having a very obstructed view of the outside from my bedroom window didn't help, I must admit.

Also I wonder if certain habits and behaviors, like dopamine-induced compulsive social browsing or gaming, food addictions, etc. play a role here.
