Studies show that when the MediaSourcePrefersDecompressionSession is set and the Netflix stream started with non-protected content.
We have a higher power usage (about 140mW extra) ; compare traces show that the difference could be attributed to how the VideoMediaSampleRenderer is only decoding one frame at a time while when a AVSBDL is in use: decoding occurs by burst.
At a glance it appears that the handling of the low watermark is broken
