Would HDR settings cause problems for SDR recordings?

By following another guide here, I've been testing HDR recordings by changing the following in Settings / Advanced:

Color Format from NV12 (8-bit, 4:2:0, 2 planes) into P010 (10-bit, 4:2:0, 2 planes)
Color Space from Rec. 709 into Rec. 2100 (PQ)
Color Range from Limited into Full

It's a lot of hassle to swap back and forth between all these settings, and when I tried to record an SDR source I couldn't visually see the difference.

Is there any reason these HDR settings would cause problems for SDR recordings? Would it use up more file space? Would it tax the rendering or encoding hardware? Any relevant info would be appreciated; still learning this technical stuff.

You can create different profiles, one for SDR, one for HDR.
Using HDR settings for SDR content will create HDR video. The colors are still in the SDR range of course, but they are not 100% as if it was a SDR recording. Might be not visible, but it's a different color space after all. And the video is a HDR video for every media player. Media players not able to play back HDR video might refuse it to play.

From a technical point of view, it's wrong to save SDR content to a HDR video, because it cannot be 100% represented. It works, but it is wrong. The correct way to do it is using a SDR color format for SDR content and HDR color format for HDR content.
