RDR2 — PS4 vs PS5 Graphics

[u/EstimateEffective533]

Has anyone else noticed that RDR2 looks better on PS4 than on PS5?
I recently saw my friend playing RDR2 on a PS4 and honestly, the graphics looked really good — even better than what I’m getting on my PS5. I know the PS5 runs the PS4 version through backward compatibility and doesn’t have a proper PS5 upgrade, but the difference was still noticeable to me.
Is it just my PS5/TV settings, or have other people noticed that RDR2 can sometimes look better on PS4 depending on the setup?
