NO SPECTATORS AT GAMES!?

As I am from Europe and does not watch NCAAB games but bet on statistical data I was wondering about public at games. As far as I can see NBA games are without public so I assume NCAAB situation is the same. During the years I learnt that home court counts and even KenPom has these A's and B's called "Tears of Joy". So I was wondering can someone of you tell me how it looks now without (I assume) public at games. That should lower home advantage is my opinion.

What do you think about this?

Thanks in advance.
