Where the liability comes in is for diesels under warranty and the owner chooses to use a non approved filter or lube oil. The Warranty can then be voided with the owner shouldering the liability.
But, on our low hour and seldom used recreational engines they will likely fail from something other than lubrication problems related to trying to save a few dollars on filters.

Thanks to the Moss Magnuson Act, the warranty can only be voided if the manufacturer can prove the failure was caused by the non-OEM filter. Manufacturers cannot force customers to use their filters under threat of voiding the warranty (unless they provide the filters for free, per the MM Act).

Cutting open a filter will yield a wealth of info, I do this routinely, I have a filter "can opener". I'd use the Yanmar filter this time, then when changing cut it open, then do the same for a WIX, my bet is the WIX is as good or better.
Having said all that, in warranty, it's probably best to stick with OEM filters, to avoid having a dispute.
Donaldson, btw, also makes outstanding filters.
I'm not vetting or endorsing this video, but it is interesting for the comparison of the internal parts alone.
There are many similar videos on YouTube.
