The only reason tone mapping is done is to make HDR footage look "normal" on SDR screens, we can't make SDR screens show any more than what the technology is limited to. HLG content is designed to look normal on both types of screens already hence tone mapping it would be pointless.
On a side note HLG technology is really limited, it only shows more detail in highlights. You might not even notice you are looking at HLG footage. I tried some demo HLG footage on my tv and I wasn't really convinced of its benefits. The real benefit of next generation tv is the use of HEVC, only progressive video and higher framerates. I've seen trial broadcasts and it looks amazing.
