When playing beat saber, I always assumed the Apple Watch over-estimates calorie burn if only because the watch is on the part of your body that's the most mobile (your wrist). So, getting 300kcal for a 30 minute session felt like cheating. But, there's at least "more legit than an Apple Watch" evidence that the calorie burn is that high; 6-8kcal per minute on Expert difficult [1], and some of the Expert+ tracks could easily burn more than that (and, I weigh much more than their Standard Reference Person). I'm not the most fit person, but I've seen surprisingly little hard evidence that the Apple Watch grossly under or over-estimates calories burned. I imagine it starts getting worse at the extremes, and nothing is perfect, and everyone is different; its an area where more research would have unbelievably high leverage (Apple has sold, hundreds, of millions, of watches) (in fact: I'm sure they've done some of this research themselves).
