Lip tie?

Does this look like a lip tie? My baby is extremely fussy around feeds, screams and cries, gulps lots of air, and I have always thought shes got a terrible latch onto bottles we’ve tried avent, tommee tippee and also mam. She’s being treated for reflux but I’ve just noticed lip ties mentioned on another site and this is her top lip?

If yes who would I need to speak to? GP or health visitor?

Side note - she wasn’t crying during the pictures, just yawning - lol
