That's because the AF depending on the angle can be very noticeable or not noticeable at all. But what DF is referring to is that removing the texture filtering, they are otherwise visually identical.
I think that right now it is evident that it is better on PS5; more stable performance and better texture filtering (the lack of AF on Xbox Series is probably the biggest problem right now). But we have to be fair, when the game was released on PS5 it performed worse than the current version of XSX. The Xbox Series X version will probably also receive optimizations in these months.
These are also differences that DF highlights:
I have checked the appearance of the water in comparisons of the PC version, and it is definitely different between "low" and "ultra":
low:
ultra:
low:
ultra:
The difference is quite similar, although not as big (between PS5/XSX). Are we sure these are the same graphical settings here?
Can anyone check it? I don't have the game.
Edit: I have seen more examples and everything I see seems that on PS5 the water is seen with the equivalent of lower settings:
