Can someone please help me distinguish if this is a leak in the wall? The bathtub is to the left of the streak and I can't be sure whether leak is behind the faucet or along the base of the tub where it meets the tiles.
Thank you in advance.

Unfortunately, it is too difficult to tell by pictures. Water always finds the easiest route, and many times, shows itself at a drywall seam.
You would be well served to contact someone for a look at the bathroom, and ceiling, to diagnose properly.
There could be a drain issue, a faucet problem, spout or shower head back spraying, or even something as simple as shower curtain, heat ducts in the area which may be receiving over spill/splashing.
