why the result of sphereface on the tSNE doesn't perform better than lcnn？

I test the 20 layers sphereface network on my own database,then test the features on tSNE that generate by sphereface.But the result on tSNE doesn't perform better than the lcnn model.However it perform better than lcnn models(I trained) on lfw database.The sphereface net I had used is trained on MSceleb database and test on lfw database gets 98.65% acc.why the result of sphereface on the tSNE doesn't perform better than lcnn？ Do you have test it on tSNE?

@xiaoxue17 I guess the default evaluation in tSNE is L2 distance, which does match sphereface.
