Yes, that works, I've done it, although it doesn't look particularly great. I think the suggestion above to apply a LUT via OBS is the best bet if your computer can handle the processing and streaming. Only a limited number of field monitors allow you to apply a LUT to the HDMI out; for example the Blackmagic Video Assist allows you to apply a LUT for viewing but it doesn't get applied to the HDMI out.
If your livestreaming involves Zoom, note that going from OBS to Zoom can be a little tricky, and since Zoom can use a lot of processing power some people advise using two computers (one to process in OBS and the other to stream to Zoom). You'd have to experiment with your computer to see if it can handle it.
