I have a Quest 2 as well. It does have good colors and picture quality, but in my opinion, not equal to the 8KX.
I use objective measures of clarity such as an eye chart world in VRChat. And this is where I can really see just how good the 8KX is versus the Index and Quest 2 that I also own.
Without this kind of objective test, the Quest 2 can seem better than it actually is.
The thing about the Quest 2 is that it has a good high resolution display, but it doesn’t have the processing power to drive it to its full potential. Not even when running over a PC link.
The 8KX, on the other hand, isn’t that great “out of the box” and needs to be dialed in well to bring out its potential. If the display on your Quest 2 seems better to you, perhaps you need to work on your 8KX’s setup.
