Where is it described which value is written as a string in the created by field?

[Meloper]

is it always the display value of the sys_user table?

@Meloper 

sys_created_by is string field and holds the userid from User record and not the name or email of the user

I don't think it's documented anywhere and not sure how it's populated. It comes from platform level and we don't have access to that script

If my response helped please mark it correct and close the thread so that it benefits future readers.

@Ankur Bawiskar thanks for your answer, so it is always the value of the userid field and we can not change it to the display value field?

@Meloper 

that's correct.
