Have tried to find an answer to the same question a while ago and here's something I came across (taken from: http://buzzerbeater.wgz.cz/rubriky/take-it-easy-vs-crunch-time). This is more about a team's attitude towards a game rather than home court advantage but you have some solid information in there about that as well:
Here are some aggregate statistics, so that we can look at TiE/CT effects as a whole instead of individual examples. These are obviously not randomly-selected games, since teams attempt to choose TiE/CT for tactical reasons.
When both teams play TiE, the home team has a record of 417-277.
When the home team plays TiE against normal, it has a record of 829-826.
When the home team plays TiE against CT, it has a record of 104-200.
When the home team plays normal against TiE, it has a record of 1262-483.
When the home team plays normal against CT, it has a record of 703-759.
When the home team plays CT against TiE, it has a record of 265-38.
When the home team plays CT against normal, it has a record of 1171-357.
When the home team plays CT against CT, it has 205-107.
not include normal vs. normal, since those will be mostly bot games, but globally the home team edge is at around 63%.

Home court advantage improves defense and rebounding. If I have to make a guess, I'd say by about 15%, but it's not something I've collected any data on.

I don't think you will be able to find anything more specific than that but if anyone knows anything more I'd be happy to read about it as well.
