River raise after betting 3 streets with flopped flush

[BorisTheSpider]

Can anyone find a fold here? All I know about villain is that over 9 hands so far he's 67/56. TBH I don't know if I can find a fold against _anyone_ it's so unlikely he flopped better - maybe a 5/5.

With his sizing, I need to call 39% which is about 80% of my flushes. Like I could call all my T high flushes, and fold anything smaller.

So yeah, can't fold from that perspective either.
