Rather than play and enjoy the game.
Look at the lengths you would go to twist reality and revise history just to fandom spiderman...Just because it turned out that the difference between SM1 to SM2 is just improved lighting.
First of all, PC games from day one historically receive 100x more features than the console counterparts and not a single soul ever called the PC version of a game "the next gen version".
PC Version historically sees improvement in Texture Quality (upto 4k textures), Resolution, Level Of Detail, Draw Distance, Reflection Quality, Lighting Quality, Volumetric Lighting/Fog Quality, Ambient Occlusion Quality, Anti-Aliasing Quality, Shadow Resolution/Quality, Particle/Effects Quality, Geometric Detail and more.
Console usually run these features at low/medium while PC has access to high, very high and ultra slider options.
A bigger gap than SM1 OG and SM1 Remaster.
And yet no one calls pc version of games "the next gen version".
To give you an example: Console (PS4/XBO) for example would have SSAO for a game while PC would have option far more expensive and far more better alternatives like HBAO, HBAO+, VXAO, Percentage Closer Soft Shadows (PCSS) and finally RTAO.
Another example is reflections:
Console games (PS4/XBO) would sometimes have low resolution cubemaps. But because the PC version has access to (high > very high and ultra settings for reflection).
You end up with features like a much higher resolution cube map, Parallax-Corrected Cubemaps (PCC), Screen Space Reflection (SSR) with various resolutions, Planar Reflections and finally Ray traced reflections.
Another example is Global Illumination Quality slider: that games like Quantum break, etc has.
Another example is PC versions having Parallax Occlusion Mapping(POM) and Tessellation..
I could keep going but I will stop.
The point is, the SM1 Remaster is the barebone difference of what a normal PC version multiplatform game would have at release. Infact as I have shown above, a PC version game would have alot more improvements.
Calling it a native PS5 next gen version is straight up cope and revising of history.
