Yes.
yt[0-9].ggpht.com
is a false positive. It is used as an alternative for YouTube image hosting. Adding yt[0-9].ggpht.com
to your whitelist it fixes everything. Without it you will not see any channel images and most images will be missing. From what I have observed yt4.ggpht.com
is used on mobile and yt3.ggpht.com
is used on desktop.
