Samsung has been providing iFixit with genuine parts since at least the S20. Although this is a good first step it came with a huge major caveat:

Screen+battery are only provided as a single assembly. You can't buy them separately.

These are the two most common repairs on a smartphone and to get a simple battery you need to buy the expensive screen.

I am hopeful Samsung redeems themselves this year especially with the introduction of the Fold5 to this program. Otherwise this is nothingburger only meant to appease regulators and legislators
