IINA has issues with color space conversions. I've heard that the specific issue is that it always (incorrectly) assumes a BT601 matrix for all videos, though I haven't verified it myself and cannot really right now. (I did verify its colors differing from stock mpv before writing this comment, though.) Various mpv wrappers exists, but for reasons like these stock mpv is the only fully reliable version.

Huh, that explains it, I was wondering why I was having problems with some video that VLC would even playback correctly, I didn't think to try the stock mpv.

Have you filled a bug report about this?

I’m not the person you asked, and I don’t have that issue, but this common trend of replying to any criticism with “have you filed a bug report?” rubs me the wrong way.

I have opened detailed issues on IINA which describe a bug, how to reproduce, and the correct behaviour (according to their own docs), and they’ve just sat there unacknowledged for years.

IINA’s issue count is twice as big as mpv’s, despite being a UI covering a single OS. Personally I don’t think it’s worth it over vanilla mpv, which I’ve recommended even to non-technical users who like it.

Admittedly I have not, but I did search for and find similar issues on their github before making this comment, and I do plan to investigate this more one day and possibly make a proper issue. There are indeed a lot of "X tool is broken because of Y" statements of varying credibility floating around in the multimedia community where it's unclear if they were actually ever reported upstream or even double-checked recently (people still claim that VLC uses nearest-neighbour chroma scaling, for example, but that's no longer true (except for screenshots, it's still a problem there)), and that is something I'm trying to work against by investigating and reporting this when I can. But since I don't use IINA myself and since, as another commenter pointed out, IINA bug reports don't seem to get a lot of responses on average, it hasn't been the highest priority for me.
