Only Saudi Arabia: a single-coloured ground.
What each one carries
Christmas Island carries a bird and a globe or map. Saudi Arabia carries writing and a sword.
How the number was arrived at
Both flags are drawn at 64×48 and cut into squares 8 across. Each square is averaged to one colour, and the score is the worst single square, so two flags that agree everywhere except one corner are as far apart as that corner, which is the right answer to a question about whether anybody could tell them apart. 0 is the same picture; the number is the worst single tile, out of 255.
On that scale Christmas Island and Saudi Arabia score 88.7 out of 255, which is the 35% above.
It cannot see everything. Both flags are stretched to the same box, so Indonesia and Monaco, which differ in nothing else, are measured as their reds rather than as identical. The look-alikes page sets out the rest.
