Monster Hunter World (PS4 pro, graphics mode, no hud)
^ This one looks incredibly blatant. Not sure how I feel, it gives it a weird look.
Here's how it looks hosted on Gifyu, a bit less dark but still not like the file on my PC:
I think the AC:O shots being unchanged is because they're already compressed by the in-game's photo mode, maybe? So I guess these host uses a compression algorithm that include some sort of colour-correction algorithm? I thought both of these hosts had uncompressed uploads, but I guess not. :\
My initial guess is that the Windows image viewer renders differently than the browser. Because when I download the Gifyu image and compare it to my original on my hard disk, they're identical (file size is slightly different). But then... I also downloaded the darkened Noelshack image, and while the file is also different, the image looks identical. I'm... confused. :D Can someone explain this like I'm five?
