This is a standard one roll action double. We may assume for simplicity that if blue hits he wins and if blue missed he loses. Since there are 23 hitting rolls, it's a clear double. Since white is winning more than 25% it's a clear take.

I think it's not hard to figure out why the second position is a marginal no double: after blue misses white will play on for the gammon, while in the first position white will cash. An average missing roll in the first variant is 10.6 pips and an average missing roll in the second variant is 11.25 pips. So, here are the typical positions after blue misses in each case:

Next, when can white still take? She certainly needs to win at least 25%, but counting a certain nontrivial number of gammon wins for blue, white can take as long as blue has fewer than 27 hitting numbers. Here are the variants with 26 and 27 hitting rolls for blue, respectively:
