Also worth pointing out that SDR HD Blu-rays are likely to look better than HDR UHD Blu-rays converted to SDR even with reasonably well implemented tone-mapping anyway.  The main reason we accelerated out decision to upgrade our UHD SDR TV to HDR was buying a UHD Blu-ray player and some UHD Blui-rays.  The HDR to SDR tone mapping was never particularly good - whatever setting you chose for it.  There is a big difference between an SDR grade done by an expert and an automatic HDR to SDR conversion.
