Has anyone else noticed YouTube’s auto noise reduction in videos?

Lately I've been posting videos on my test YouTube channel shot on older 4:3 cameras for my show, and I've noticed that when I play the video back it doesn't match the original version straight from my editor. The noise in my footage was either automatically reduced by Youtube or was compressed to the point of certain details in the footage (such as noise) being lost. Now all my footage looks more modern and almost cropped to 4:3 because of the lack of noise showing up in the test video (ruining my trademark 80s look). Is anyone else having this problem?

 

Most obvious example would clearly be: testchannel1 outro1                  which clearly has auto noise reduction

YouTube has done client-side normalization for a few years now.
