If she said it like you wrote in your post, then I don't think it's appropriate.

My T doesn't give me much compliments. Especially not on my appearance. The only things that came close was that she said she doesn't think I'm fat. That was after I talked about that I think I'm too fat.
She sometimes comments on how I look, but it's like ''I think this is the first time I see you in a shirt without sleeves'' or ''your hair looks different'. But she doesn't say if it looks good on me.
I wish she would tell me what she really thinks of me. I don't want her to be so T with what she says all the time.
