I think they were trying to portray then as a sikh family as mentioned my another person @1987Roso there are many things that are Shown which are not practiced in really life.
Sikh family can have people wearing turbans but men also have their hair cut as well. I think a lot of things are hard to show and you have to be careful with religious sentiments and not to show anything wrong. Chooda is definitely what Sikh newly wed wear but I think the length depends on the individual. I have seen some wear it upto a year
