Yes, the texture for Earth with clouds actually looks like that in some newer versions of Redshift.
After almost a year trying to decode the textures from older versions of Redshift, an old astronomy software, and reprojecting them, I'm proud to announce the release of this texture set! Please note that this isn't an add-on, it's just only the textures. The add-on and the un-reprojected decoded textures can be found below this post.

In the zip file, there are two folders, "old" and "new". The "old" folder has textures that are from Redshift 3, while the "new" folder has some textures spanning from Redshift 4 to Redshift 7 that replaced the old ones. Almost all of the textures are nearly 2k (although the poles have less detail), and some are scanned shaded relief maps. The weird seams at the poles are caused by the UV map being offset, just like in the software. Some textures are shifted, especially the new ones.
There are some duplicate textures (specifically Venus, Earth, the Moon, and Mars) that have a higher resolution than others, but it's because those 4 have higher levels of detail in the software. The texture for Saturn's rings isn't there because it uses 3 separate files with a format that I can't decode. However, I could recreate it. The texture for Earth's clouds is combined with the surface texture because the software used the JPEG format for the textures.
Also, here is a Python script for decoding and encoding the textures for Redshift. I might release some other tools soon.
