iirc part of the point of moving to 4K sectors is to improve the error

Frankly I wish they'd sacrificed a little storage density and improved the
error rate a long time ago.
Looking at the data sheet for WD20EADS and WD20EARS they both have 10^15
"non-recoverable read errors per bits read", so at least in the data sheet
nothing has really changed in the error rate aspect.
