I do not know whether or not VAR is affecting the ability or willingness for onfield officials to make decisions, only they could tell you that, however, their answer should be that it makes no difference.
I can tell you that De Bruyne was cautioned for the offence leading up to the penalty, although that took some time if memory serves me correctly, possibly because of it showing the VAR reviews.

Next season De Bruyne would escape the YC (assuming it was for preventing a promising attack) because advantage was played.

As for the original question: I don’t watch a lot of rugby league but I said when VAR was coming in that in many rugby league games what look like very simple decisions that I’d expect a referee to see are referred to the video referee. Even my untrained eye could see what the decision should be and rugby league referees because of the nature of the game are rarely poorly positioned. I predicted football referees would be the same especially as I suspect the head of PGMOL might not be supportive of an official who makes an error.
