Have you been watching any of the EPL this season? VAR has not changed the decision on any of these kinds of incidents.
The referees (and these aren't refs who magically get better because they are sitting in a VAR booth) who review the decisions are set the standard that the on-field decision has to be "obviously wrong". They have been taking the stand that literally none of the decisions are obviously wrong and letting all the original decisions stand. Even when there have been blatant penalties and obvious violent conduct fouls, no action has been taken.
The only time VAR is changing things is during the mandatory review of a goal where sometimes they are being disallowed due to an offside or a foul in the build-up. And even those are controversial when they are tight. Partly because it's a human being rather than a computer that draws the line on the screen to assess offside decisions. So the decision can be different depending on who draws it and where. And partly because the resolution of the images means that you can't freeze at the exact moment the ball left the passer's foot.
The biggest issue, however, as I mentioned above is that it's the same pool of Football Association refs reviewing decisions that are refereeing games. So the same level of incompetence is applied.
