SOLVED: Jellyfin has washed out colors (Violet Evergarden)

[voltangle]

UPDATE: did a bit more testing, and turns out - Violet Evergarden is not the only one with botched colors. I have not tested everything (there is shitloads of content in my library), but basically all of them have colors that are less saturated than what IINA gives me. Also, there is in fact no difference if I play the video via URL streaming or SMB, literately zero, i'm a bit stupid, sry guys

Honestly, I have no idea what is the culprit - media players tweaking for some reason, IINA showing stupid colors (and I see them as fine because my display is fucking dogshit), or I'm just tweaking at this point

If @gnattu is right and he actually sees my IINA screenshots as dark (ones without any filters applied), then I'm tweaking together with my monitor
But I honestly doubt that because I don't believe that Violet Evergarden actually looks this washed out originally, and AFAIK iPhone Xr, even though it's an LCD panel, has very good color calibration, so it should not be even an issue
@TheDreadPirate how do you see the colors on my screenshots? Is the IINA screenshot really darker than it's supposed to be?

I'm so lost man, where tf am I supposed to look and what am I supposed to believe and trust as "correct" colors...
