However, regarding the part being wrong to use SPHERICIAL, I think that you are wrong about that. The texture is definitely not designed to be used as a Mercator projection. Switching to CYLINDRICAL squishes everything vertically. And while I don't exactly understand why, the lines of latitude are correct with SPHERICAL projection in this part. (Just look at it directly from the side with the original SPHERICAL projection.) While using CYLINDRICAL with an appropriate texture would probably make more sense, the existing texture is definitely not right for that.
Your proposed CYLINDRICAL looks like this (after me flipping things in LDView's code):

The original SPHERICAL looks like this:

Both images were taken with LDView's FOV set to 0.1.
Notice that all three visible lines of latitude are horizontal on both images. Notice also that the spherical one has more correct aspect ratio of the map. (The cylindrical one has the continents squished vertically.)
