Seeing comments on 3rd gen learning thermostat being compatible with 7-wire systems, but want to confirm with the attached image if the base Nest model is compatible. Thanks in advance!

Well, i tried attaching my image but I can only assume it was over a size limit or something and then i could no longer edit the post. Google Lens rescued me by finding a match from a Reddit post. They're saying it's not compatible on Reddit, but I trust this forum more.
