if you're interested in Max Fleischer's Gulliver's Travels on Blu-ray, then get the
Thunderbean Animation version of it.
avoid the Koch Vision version of it.
the Koch version is distorted. it has the incorrect aspect ratio. the colours are not as rich. and it is a tad too heavy handed in dirt/speck/grain removal.
look for yourself at these comparisons:
the only thing in favour of the Koch version is that it has 2 Gabby cartoons (Swing Cleaning" and "King For a Day") in HD.
