I thought also a problem while advancing the film... however, what's a ruby window? i think the bronica ETRS doesnt have any... Good news for me is that all of you think is not a light leak

Hi everyone, Don't know if this is the correct place for this question, i did not find where to put it. Sorry for my bad english in advance. I've just received the scans of a pair or 120 rolls i shot with my bronica etrs. I hadnt used this camera since 7 or 8 year ago. I've sent the rolls to be developed and scanned at a little lab here in my city and, when inspected, i started to see there are some strange light variations in the sky. I've search all across the internet for info about light leaks and dont seem to me this is my exact problem, but i'm hoping you could help me. In the meantime, i have written the lab to re-scan or check the negatives once more. Both rolls are not expired, one is ektar 100 and the other portra 160. In both there are issues, but in portra more "dots" type than in ektar. Ektar was just finished some hour ago before i put in the hands of the lab. Here are some crops. I have made some strong contrast curves and clarity in lightroom so the light variations could be seen better, but i'm putting also the original images where you can see the problems too : I hope some of you more expert in film photography and negative scanning could help me here. The lab claims to have a Noritsu HS-1800. Another thing i dont understand and maybe you could help me too is that, even the send me the scans in tiff 16 bit, they embedded the sRGB profile on the images. Isnt that a little strange? if i want 16 bit tiff, i assume the profile must be also wide, not the sRGB... what do you think? Thanks a lot
