Version control doesn't notice textures change size

Hey everyone, I’m using TortoiseHg (Mercurial) for version control and have another artist who downsized some 8k textures to 2k, re-imported them and re-saved the .uasset textures. TortoiseHg noticed changes and I pulled the changes and updated my working repo. The texture sizes didn’t update on my end and are still sitting at 8k. Is there a reason why version control can’t notice changes in textures sizes? Is this just for .uasset versions? Any advice is greatly appreciated. Thanks!
