It looks like 4.1 does a better job at demozaic.
The pictures below are processed by, from left to right, 4.5 (tif), 4.5 Pro (tif) and 4.1 (jpg 100%) under the exactly same settings. I don't have 4.1 tif fomart.

  I'd say it looks like 4.1 is just smoothing the neighboring color components together more, and that 4.5 could retrieve more detail. But without a TIFF from 4.1 it is impossible to say, the JPEG compression throws out and ability to do pixel-peeping comparisons.
  
  How do they look at 100%? Printed? That's what matters.

  I tried JPEG output at 100% from 4.5 Pro, the maze in the letter N still exists.
  It's not a problem of JPEG compression.
  
  At 100% zoom, the maze problem is barely noticeable.
