I would not be concerned about using this mix on a Paph. There are several ingredients in it to promote aeration and Paphs, as terrestrials, can withstand a wetter mix. I know a hobbyist who has them growing successfully in nothing but fine coir. Just water accordingly.
Many companies put out mixes supposedly geared for one specific genera. The truth in many cases, is that they only change the name on the bag.
There are as many successful blends of mixes as you ask growers, and many growers use more than one "blend", which they make up themselves as they learn the needs of their plants.
Remember, the only reason we put orchids in pots is to keep the from falling over!
