I suppose I could look it up, but I'll just ask you... why?
I haven't heard this and still go in the 131-134F range then do a quick sear either on my grill at max temp or cast iron skillet if I can open the windows.
It seems the enzymes/processes that render fat accelerate around that temp (not hot enough to really melt it). So specifically for ribeyes which have a lot of fat, you trade a small amount of moisture loss for more buttery/rendered fat.
If you've had ribeyes sous vide with a bit more fat than you'd like, you can try 137. If you enjoy them fine as is, it's not going to melt your brain or anything (134 works perfectly great). I wouldn't do filet mignon or flank that high because the moisture loss isn't made up by gaining more rendered fat.
