The new Infuse upscaler has improved this upscaling process. So unless you only watch 4k content in Infuse, you WILL benefit from the new upscaler. Whether or not you notice a difference is another question.
Most of my Infuse activity is on an Apple TV 4, connected to a 1080p TV. I do have an Apple TV 4k, and a compatible TV, but because the sound bar only has HDMI 1.4, I run everything through the TV, and out optical. The Apple TV has to be set to Dolby digital 5.1 in this setup to even do 5.1 sound. The Roku can pass directly through the TV standard DTS, and DD+ which the TV converts to standard DD and sends out the optical. The Apple TV 4 on the 1080p setup can be switched into the HDMI input of the same model sound bar, so I get the standard codecs, and PCM 5.1. So, since most of the content I watch locally is HD, or SD, right now it's more practical to use that setup.
When it comes to 4k, I have a Sony UBP-X800 with dual HDMI outs so that gets the HDMI input for the 4K setup. So, I can still get lossless audio with 4k, but only on physical media, and having the player decode internally and send as PCM, or I can have standard codecs too.
My point in explaining all this seems to come back to while I enjoy HDR content, it would have been more practical for me to stick with HD only for a while longer.
After saying all this, would the inFuse upscaler make much difference in an HD setup? say SD to HD? Or, is it more for 4k?
