For PlayReady, we strongly recommend that you use the post-delivery method, not the pre-delivery method, in the OTT streaming service. The non-persistent license is not provided on webOS TV 3.0, 3.5, and 4.0. Note that Widevine Classic will be deprecated from webOS TV 23. You should no longer use this solution. For more details on DRM, see DRM Content Playback.
