Not a lot to be learned from a day of the week breakdown (not that I can see anyway).

Just lumping all tracks together for 10 years, NSW Tab returns on a dollar invested on all horses in all races (about 1.4 million in all).

Sunday, All tracks 79.14% Metro only 79.27%
Monday 80.51% Metro only 79.73%
Tuesday 78.99% Metro only 76.68%
Wednesday 77.34% Metro only 77.91%
Thursday 80.31% Metro only 79.79%
Friday 79.16% Metro only 78.28%
Saturday 78.77% Metro only 78.89%

Sorry, too hard to program public holidays or whatever.
