Why is Texture downgraded when imported to UE5?

Hi, as you guys can see below, My texture is getting downgraded when I import it from any other software, the one on the right is quixel mixer’s, left one is original UE5 material.
The material In mixer looks really good, but when exported to ue5, it looses some of its sharpness and overall quality.
any fixes? because i cant rely on ue5 itself because it’s limited when it comes to texturing
