Great idea!!
Few errors I spotted:
1) Pixar Short Films Collections (both volumes) were never released with Digital HD/SD (both should be marked red).
2) Cars Toon: Mater's Tall Tales was released only in SD as part of the Cars boxset (should be marked blue).
3) The Tigger Movie had a digital SD code in it's 10th Anniversary DVD (BD never had a code).
4) Both
Pooh's Heffalump Halloween Movie and
Once Upon A Halloween were never released on BD (should be marked orange).
