I remember that happening with Katakana where eventually I started to notice the patterns and what syllables the symbols represented until eventually it just started auto-translating in my head. Now I just kind of read Katakana as if I was reading it in standard Roman lettering. It's kind of strange and weirds some friends out when I'm playing some import games cause I'll say things like "Okay now go to options" and they'll just look at me like "Really....
" and I'll be like, "Oh right sorry..."
One other thing I've recently noticed though is that I can sometimes pick out when characters are using archaic or extremely formal or unusual dialects of speech in anime now too. I definitely can't just watch with subtitles off, but it's fun picking out those small little details every now and then.
