The real issue isn't specs but cost.
The Quest 2 is the single most widely used VR headset in the world with the Quest 3 and 3S right after it. While these are goo devices, it's telling that the Quest 2 - with noticeably lower resolution and performance - is the winner. That's because it's the cheapest of the options and people who bought one, if they're still using it, do not feel compelled to upgrade.
The Quest Pro was a flop not because of its specs, but because of its price. The upper limit for a consumer grade VR headset is around US$1000. That's not to say headsets over that price won't sell, the Apple Vision Pro has sold , although the highest estimate is maybe 300K units before returns, which we know were many compared to the 10 million Quests.
Unless the Galaxy XR starts below US$1000 and preferably below US$750, it will be much like the Apple Vision Pro - a niche product looking for a consumer, but without the Apple fandom behind it to bolster even the AVP's small success.
XR glasses are the future. These are just intermediate products, confirming that technology is still not there (especially battery, it's ridiculous to carry around this brick with you lol). Try using them for several hours a day for work and you'll kill your eyes in one month - ask any doctor. And then yes, price comes into play. Everyone I know who bought VR - used it for just 1-2 months and then it collects dust. These glasses application is too limited for the price they ask.. Also I have big doubts that samsung/google's software will be stable and polished in this first gen project. And after a year google will kill it because of low sales.
