While looking at Colorspaces.cpp TfFromLinear and LinearFromTf functions I tried graphing the equations and found the <0.5 range math seems to be wrong, the few references for this on the web (even the spec) also seem wrong by my reading.
We don't currently use HLG here but the math should be corrected.
