Short description of error
When any Attribute Node is placed after the "point instance", the instances don't respond to the Vertex Color information. They don't lose the information, they just don't respond to it.
Exact steps for others to reproduce the error
When using geometry nodes, after instancing objects with the node "point instance", the instanced objects don't respond to the information saved on Vertex Color's itens. On the spreadsheet, it's possible to see that the information is still there, within the instances, but it doesn't read it or respond to it. I've linked a short video demonstrating it and how it works on Blender 2.92. In either versions, GN isn't able to manipulate Vertex Color information.{F10160392}Blender 2021-06-06 22-15-43.mp4

The problem is that when the instances are made real by the Attribute node, the vertex color layer is turned into a "generic attribute" that is not yet supported by eevee.
