Question Problem with Color Lookup

I'm trying to implement color blindness filters into my game for accessibility, and I figured the best way to do this would be with the color lookup post processing effect. So I applied my filters, but It didn't look quite how I expected, everything very high contrast and bright colors, not how I'd seen these types of filters looking before. So after a while tweaking my LUT files thinking they might be the problem, I decided to try using the color lookup with a neutral LUT (which shouldn't do anything to the image) in order to see if something else could be the issue. And this is what happened, first picture is without the effect turned on, second is with the effect turned on and a neutral LUT.



I'm using URP with these setting:



And these are the import settings for the LUT files I'm using:



Does anybody have any idea what could be happening here or how to fix it? Thanks.
