Nobody knows but here is Mazda North American Operations' PDF to their US Mazda dealers concerning genuine oil filter's installation on SkyActiv-G engines:
Here is one MNAO PDF to their US Mazda Dealers concerning genuine Oil Filter(s) installation and use for ALL SA Engines..
Mazda Dealers (in USA particularly) are also seeing stored DTC's (Diagnostic Trouble Codes in PCM) when they use even 'other' genuine Mazda oil filters in Skyactiv engines, see pic, they look identical, but it is what is inside.
Here is product specifications on Wix 57002 which is custom made for Mazda SkyActiv-G engines and it should have similar specs as Mazda "high-flow" OEM oil filters such as PE01-14-302A:

And here is product specifications on Wix 51365 which is equivalent to Mazda conventional OEM oil filter B6Y1-14-302A:
