That's why I use this metric. Instead of a boolean "is/is not photorealistic", this gives us a way to measure progress.
I've seen some radiosity-based architectural renderings that have me fooled at about 800x600, I haven't seen anything in motion that has me at that resolution yet, and even the architectural stuff still breaks down at 1024+ (the models are still too clean).
