No it isn't. You say removing penalty goals highlights Ronaldo's lack of contirbuiton, now even if I agreed with that (which I don't, the painting of him as an inzaghi type forward is only reflective of his second spell here and maybe some of his time at juventus) there are hundreds of other metrics that could highlight that, assists, key passes, dribbles, that would be more reflective of an all round game, so why would removing penalties from his goals be used to show a lack of an all round game when you have other stats that would be far more useful to determine this.
When you're talking specifically about goalscoring, to include penalties for one player and not another, is just about the beat example of hypocrisy you could find
Nobody painting Cristiano as an Inzaghi type forward here. But since 2012/13 or so he has drastically reduced his involvement and is almost exclusively a final third or even box player. That's simply a fact, nothing agenda driven and pointing that out doesn't mean you liken him to Inzaghi.
Why do you think people spoke of non penalty goals? To highlight Messi's superior contribution from open play in comparison to Cristiano's. What would be the point of bringing that up in the context of the world cup? To prove that Messi didn't contribute from open play? Well, that's proven wrong in a heartbeat. It is just redundant. Not everything revolves around Cristiano, you know.
It is as if we had a discussion about which car was better, yours or mine, and then I say 'I prefer mine because it has four doors and yours only two'. Then one year later we walk fown a street, see a Ferrarri and say 'damn, that car is a dream of mine' and you go 'you fecking hypocrite, suddenly two doors aren't that bad, right?!'
