if you're talking abot change at sunrise and at sunset, on most devices you have to calculate that yourself in the DF. With system 5, you can use Weather.getSunrise() and Weather.getSunset().
When you have this info, it really depends on how you coded your DF to change the colors,
In a simple DF, your DF should act like the native ones for that device in this regard
I am using an EDGE 830, and I want to confirm if the datafields background that come originally in this devices depends on a light sensor? or how does the night/day mode work in this device?

Do these functions use the internet? If they do, it would be kind of "expensive" for such a basic need.

That means "internet stuff" (generally) and having Garmin Connect Mobile running and connected.
The devices can calculate sunrise/sunset internally. Hopefully, the "weather stuff" uses that but I'm not sure it does.
If "internet stuff" is required, one might not want that complication just to change the background of a data field. You might not want users to have issues with something they don't expect to require "internet stuff".
You only need to get rise and set once. I suspect the native stuff uses the same thing. You can calculate it yourself (I do that in watch faces) and only needed once a day, but takes code space.
