is this a complement to trans people?

I accidentally put this in the wrong community 😭 but I myself am not trans but l've had this question on my mind and wanted to ask actual trans people. Is it a complement when a person says "I couldnt even tell that you were trans/l didnt even know you were trans"? I've tried to ask trans people on TikTok but I was just getting ignored 😭. Thank you for reading! Edit: just wanted to add that I never actually said this to a trans person - don't worry. It was just a thought I was really curious about.
