I too think that this is a penalty, but agree with
@RustyRef in that this would not meet the threshold for a VAR review.
I had a discussion earlier this season (in my previous county), with an SG1/SG2 AR about VAR reviews.
He, given he is familiar with my background in Statistics, informally equated the bar for VAR intervention to the concept of 'statistical significance' and 'confidence intervals'.
Without getting into the maths excessively, what this means in practice is that for a VAR to get involved, they have to be 95% or more sure, that the referee has made an error in their on-field decision.
Later in his presentation, he gave a worded example in the discussion (to illustrate the p<0.05 point).
'The threshold for VAR intervention is, you ask a room of twenty Premier League Match Officials whether the referee has made an error. You should get at least nineteen of them to say, "yes that is an error, go have a look at the monitor" before you are recommending a review'.
