I only use the built-in diffing by Playwright. It comes with a nice overview page [0] that shows all the failed tests including traces and screenshots. There you have a pixel diff. If you have some notion of irrelevant changes that shouldn't warrant a test failure, I wouldn't know of a way to pull that off.
