very pool quality in webp

extremely unpleasant to find the whole site in low quality, they say the webp quality standard is 75%, but that doesn’t seem to be true, I work with photoshop for years and 75% quality is quite a thing, the images seem to have 25% quality, because it is very unpleasant to the eyes, I checked the box to 85% and the jpg compression noises still continue in the files that are now webp, a very lazy service on the part of the developers, they should review the practices used in the engine of conversion, as it leaves something to be desired.
