Were there though?
What title was ever decided by a genuine on-field clanger in recent memory?
The only one I can think of is when Howard Webb made up a penalty to give to Manchester United in 2009 when they were 2 down at home to Spurs at half time. But even then, United ended up winning 5-2. And the title by several points. So it probably didn't really make that much difference.
VAR was created to solve problems that weren't really there. As far as I can see, the only ones to really benefit are the TV companies, who stand a better chance of getting a few talking points to discuss during boring 0-0s.
