Any read on Button here?

I almost always call this down. I think you are best here enough to justify calling the river bet (though it is a crying call). You really only need to be good around 8% of the time anyway.

NOTE: There are a combined 9 ways he has a worse set here and only 4 ways he has AK. I suppose if you knew he might cap PF with AQ, then you can add in 12 ways he has AQ. Either way, calling the turn and river is a good move.
