Whoever from samsung reads this let me tell you, the moment you include systemwide material 3 expressive design for samsung's one UI your sales will shoot up faster than a rocket.
1.There are millions of people who love samsung but just because they love pixel's UI more they tend to switch to pixel even if it means compromising on performance.
2. If samsung brings pixel like ui design to samsung ( especially material 3 expressive with android 16 ) people will fall in love with samsung because samsung is way ahead in terms of other aspects like performance.
Yes you cannot copy it but you can definitely get inspiration from pixel's UI. Like samsung copied iOS like notification drop down ( separate panels for quick settings and notifications ).
