Swapping layer preview from flat texture to a ball doesn't make sense

I've been using Substance painter for years and very often I need to color pick from another layer's preview. Now that there's shaded balls previewing the layers, I'm unable to color pick cause I have the entire spectrum of a ball to pick from. The ball doesn't make sense, please just bring back the flat texture. 

Also seeing the mask preview was really great but I guess that never comes back.
