Non-scaling client?

is there a Channels DVR client that does NOT scale 720P and 1080i? I'd prefer to have the iScan Mini do the scaling. It seems like most non-4k streaming boxes want to turn 720P into 1080, which is just wrong, as if you keep it at 720 it scales 1:3 into 2160 later.

This is not a function of the Channels app but rather the underlying Apple TV or Android TV OS. I believe they all run at a fixed 1080p resolution in non-4K mode.

Yes, I know it's not a function of the Channels app, but users of all the various boxes are here to ask.

As far as I know the behavior is the same across all the boxes since they run the same OS. But maybe someone has a different experience they can share.
