Discoloured mod thumbnails in Library

[insomnious]

Bug Report

Summary

(Summarize the bug encountered concisely ensuring you state the current behaviour)

When displaying mod images on the Library page (thumbnails-in-pages branch), the images have a blue tinge to them.

Steps to reproduce

When running the thumbnails-in-pages build...

• Install a mod
• Go to Library page
• Thumbnail next to Name doesn't match the one online

What is the expected behaviour?

The image matches the one found on the site.

Other information

I did some quick research into the issue and it is stemming from how we Encode and Decode the image from the site into and out of our database.

https://github.com/Nexus-Mods/NexusMods.App/blob/thumbnails-in-pages/src/NexusMods.App.UI/ImagePipelines.cs#L174-L174

When I changed CreateModPageThumbnailPipeline() in the ImagePipeline to use SkiaWebp to Encode\Decode, the images work fine.

When using QoI, if I manually set DecodeQoi() as Bgra8888 instead of Rgba8888, it also works.
