I'm sure there are massive potential gains that can be squeezed out by real-world encoders. Something like x264 and x265 can run rings around the reference encoders with real-world long form content using real-world parameters, and still be orders of magnitude faster.

It just takes a whole lot of development that's out of scope of defining a bitstream to get those gains. Codec development focused on PSNR @ Constant QP also runs the risk of over optimizing for a design where QP correlates highly with PSNR.
