That's irrelevant.
PS5 and those other devices are different. Sony has only ever said 4K/120 PS5.
Gears 5 is NOT true 4K @120 so of course it looks better 4K/60.
I personally find it still amazing in it's pseudo 4K/120 mode.
They never mentioned, that this feature is only supported on a PS5...
And somehow you are missing the point.
It is not about if the game looks better or not in 4k120hz compared to 4k60hz.
It is, that at 4k120hz the TV halfes the horizontal resolution and therfore the picture itself in not real 4k anymore.
Let us put the consoles to the side and look at the PCs with RTX30xx and RX6XXX. Even on Desktop it is blurier than normal 4k.
They have all the same issues. And if only this TV and other TVs with the same chipset suffer from this "blur", then it is the fault of the TV. All other TVs, like Samsungs QLED, LG OLED and Nanocell etc. work fine.
And again: If you cannot see it, it is fine and I am even happy for you all, but this does not deny the fact, that the TV is still missing features and the 4k120Hz is not working as it should.
Even with this Issues I still think it is a good TV, but the rival TVs currently are able to support all of the broken/missing features.
Edit :
To show what I mean and how the blur is visible, I even provided you all 3 different videos/articles.
Or try googling xh90 120hz blur, you will find enough evidence
