That's largely speculation.
Also if they thought they had 4GB to work with and 2.5GB was used for the OS then they were allowing 0GB free for general game data and other assets. If this is how they plan to use 4GB why wouldn't they use 5.5GB for VRAM now they have 8GB, since apparently they didn't need to leave any memory for game data.
So maybe 3.5GB for VRAM is low, maybe it's more like 5.5GB VRAM.
Simple.... PS4's OS was only allocated 512Mb back then....
