Ruby makes this whistle exhale noise

[Iseitaku]

I was handling Ruby at one point and she was making this audible whistle like loud exhale at times. I had shifted how I held her (she inherently coils around the wrist so easy to handle her one handed, although I do have a second hand ready incase she needs it.) and somewhat guided her to uncoil around the wrist and it seemed like it lessened a tiny bit but she still made the noise. I examined her nostrils and I noticed one looked somewhat off.

Is this a sign of RI or just her hissing at me?

(I am leaving her be for a while to test this theory as she is the "vicous" one of the two that I have.)

I'll post the pictures below in the reply
