The present disclosure is directed to systems and methods of transferring bulk data, such as OLED compensation mask data, generated by a source device to a sink device using a high-bandwidth embedded DisplayPort (eDP) connection contemporaneous with an ENABLED Panel Self-Refresh (PSR) mode. Upon ENABLING the PSR mode, the source control circuitry causes the source transmitter circuitry, the sink receiver circuitry, and the eDP high-bandwidth communication link to remain active rather than inactive. The source control circuitry generates one or more data transport units (DTUs) having a header portion that contains data indicative of the presence of a bulk data payload and the non-display status of the bulk data payload carried by the DTUs.
