On the MSDN and Technet pages there are some default CRM version text in the header and footer but make no misstake, you can only do this change in a CRM onprem environment where you are the deployment admin.
As the change is deployment wide and you need to have deployment administrator access rights, you are also extremely unlikely (unless you have a dedicated Online environment) to get that set.
