Is that worth $400? What question is that? The price difference to a normal PS4 is $100 - $200, not $400.
Better AA or even supersampling is already a big improvement. Plus less slowdowns in problematic titles. Plus better performance for PSVR. Probably less noise than the first PS4-model, too.
Also a fresh warranty and higher resale value for people switching from their 2 - 3 year old PS4 model
