Since the SAP of both types of olive oil is almost the same, along with the supposed qualities of the finished soap (hypothetically, according to what we have in the calculator's database), I wouldn't worry about that too much. I use a similar blend and always input it as just pomace.
If it's out of concern when it comes to labeling and the order of ingredients - I don't think mentioning the exact type of olive oil used is a must, just olive oil should be enough (I may be wrong here though, it's just a speculation on my part and someone else may chime in and say otherwise, I'm curious).
Either way, it would be really hard to practically impossible for someone to find out the ratio (unless the manufacturer stated it somewhere, on the label or on a website). If you really must know maybe you can get in touch with them and ask? HTH
