> The main reason I stopped using Lineage is because I got a Pixel and wanted to keep maximum picture quality with it.
I think if you get a Pixel, then you should use either Stock Android or GrapheneOS. I don't see the point in using something else.
> Is it enough to get the Google Camera APK somewhere else and use it?
With GrapheneOS, you can install the Play Services, the Play Store and then the Google Camera. I would be surprised if that wasn't enough. In fact I would be surprised if you needed more than the Camera APK. But like you, I haven't made the comparison. Would be interesting!
