Been done many times.  Because it's a good combo. Heat treated high quality bamboo surpasses wood in compression abilities.

I think I read that the bamboo needs to be charred black when you heat treat it??

I think the charred black look is overkill, from the days before heatguns, where people used blowtorch set ups for tempering. Not necessary to go that far and you still gets the performance results.
 If you are not already aware you only temper the belly lams, not the backing.

Slaughtered and quartered a steer snagged me some sinew and the hide been scraping for three days now but got some thick long sinew more than enough for 2 more layers of sinew plus a string... I hope

if you have another slat or scrap of that bamboo, you might try putting a moist cloth or something on the same side as the sinew was applied. look to see if the moisture creates the same effect. my guess is that it will come around the way it's supposed to when it gets a bit drier. did you toast the bamboo before applying he sinew?

Pretty sure it is the moster that's got in the wood but I'll not sure.
