Figured out how to get PNGs without a USB.
There is something reducing the IQ on PS5 - both PC and PS5 have CA on and just look at the fine detail in the hair on PC compared to PS5. Maybe the TAA, maybe reconstruction, maybe DRS.
In stills it is only ever as bad as this screenshot in direct light but it is very obvious in motion if you have decent vision.
Crops of the PNG so Imgur doesn't mess with them

The full size PNGs got converted to JPGs by Imgur but included to see I haven't done anything funny.
I'm playing on PS5 and the IQ is definitely more than good enough but you can easily see the very low resolution RT in RT mode and the grainy hair in all modes so if it is native then Capcom have done something to that makes it look worse than native.
Here's a darker shot that doesn't look like checkerboarding so maybe just DRS but whatever it is you'd have a hard job not noticing it in motion as there is obvious shimmer.
