By the way, no review of the TMP blu-ray claimed it had excessive DNR.
Treks 3 & 4 had the excessive DNR.
Trek 1 and 2 were praised for having the most film-like appearance of the 6.
That's what I'd heard too; I think some people mistook all of TMP's soft-focus shots to be the result of DNR.
Some of the VI screencaps looked pretty awful, though...one of the shots of the final bridge sequence (under Kirk's last captain's log) looks like watercolor paintings as a still frame.
