In my opinion, is not worth to change from Studio Display to Dell 6K, but someone like me using iMac 5K for a very long time and wanna upgrade from Intel to ARM Mac, I think is a very good choice. iMac screen compare to ASD is nearly identical(I watch many reviews from the web and went to the Apple store to compare it by myself too), I also consider to buy a XDR but it is a 4 years old product and is double the price of the Dell, I love glossy screen too but after 2 weeks of use, matte screen isn't that bad, color is very accuarate, less glares and my eyes feel a lot better now(maybe cause of the bigger screen). Double the price for a same resolution monitor, does it worth to pay that much, what if a new model XDR coming out later this year. this is why I choose Dell 6K instead of ASD.
