The comic doesn't explicitly say that he was using the Power Gem. It was just glowing throughout the entire sequence. I haven't read the issue yet, so I don't know if that was just a visual representation or a visual cue that it was being used. It does not contradict anything from those particular scans. Because, if the gems are always glowing like that, it's an even more blatant showing of Thanos making Hulk his b*tch.In the movie, it's perfectly clear when Thanos uses the stones. He closes his fist, there's a sound effect and the stones do their best Rihanna impression to shine bright like a diamond. That's harder to show on paper more clearly.
Regardless, the Russo's said that Thanos is stronger than the Hulk on one occasion IIRC and in the interview I posted, said he's as strong as the Hulk but far more skilled, dismantling him with easy.
