Help Youtube HDR upload looks bad on SDR Monitors (good on hdr monitors)

So I finally was able to start uploading video to youtube using the HDR settings in the x.265 codec (main 10 profile and rec.2020 with high dynamic) and they look great on my 4k HDR tv, however, for anyone watching on a standard computer the SDR looks really dark and bland.

Youtube is supposed to have a built in SDR converter but its doing a very bad job.

I have had to resort to start processing the video twice, once for HDR and another time for SDR.

Here is my HDR video:

Is there any other method of doing this, somone said there is a way of including a SDR lut? How do I do this?

Currently my video is graded and then exported, I then manually upload the file to youtube. Not sure how I specify an SDR lut, also how would I even make the SDR lut to begin with?

Thanks

Well...that's just how it is.  You need an HDR monitor for HDR material.

You also need a second grade for SDR.  It's not as simple as applying a LUT.

Yeah thats not good enough, see here:

Upload High Dynamic Range (HDR) videos - YouTube Help

Look under More Control over SDR conversion, but this is very specific to Davinci Resolve.

I would need something like this for adobe, where It has a SDR conversion lut that can convert the HDR output to SDR (the same way it would have been had I chose the MAIN color profile instead of MAIN10).

Right now I have to upload 2 versions of each video! an HDR version and SDR version because the HDR version converted to SDR by youtube looks so bad.

ADOBE what are you going to do to address this, youtube has a way to assist in SDR conversion we just need you guys to come up with something that does the same.

Maybe have an option for CONFORM to SD where it spits out a LUT to convert the HDR output to SDR?

YouTube is offering a gimmick.  Even they admit the results won't always be good, and who knows if the "good" ones are accurate.

You need two grades if you want to deliver two versions.
