True, it's likely just a preference too. It could be because HDR allows for a more natural and wider range of color and luminance which looks realistic, while the more compressed SDR feed makes it looks brighter and more poppy if your eyes haven't adjusted (in reality there's less range but the overall bottom is raised). People do usually prefer more pop in video games, but similar to how compressed music sometimes appears louder and we associate louder with better. Or like when our eyes are used to Vivid picture mode etc. At the end of the day, we all have our own preferences
