I find that a convoluted way to view things. Reviewers play the games to get a sense of what they're like viewed live, then record multiple solutions and spend time analysing the images and video side by side, looking for what is most stable in motion, what is less blurry, has less artefacts etc and so on. It's fairly straight forward to see what some get right and what they get wrong, and then articulate the differences and perhaps even rank them accordingly. Right pixels, pixels in the wrong place.. this is jibberish adjacent. None of these are perfect, there is no ground truth reference image to compare them to for the 'right place' for any given pixel to be.
