roTextureManager and HTTPS (lag)

Any update from Roku on this? I just tested again, and https seems to work without setting the certificates on a Roku 2 - 2720x (this was not the case back in May). It still takes ~200-300ms if I set the certificates on the roTextureRequest with the default bundle. Is it possible a firmware update in the past few months has added support for https urls without setting the certificates? This has been impacting our channel on basically anything other than the Roku 3, and 2015 Roku 2. If a firmware update has fixed it, great, we'd just like to know so we can safely drop SetCertificatesFile() from the roTextureRequest for models on that specific firmware. If not, can you get some further assistance finding a valid workaround?
