I’ve said it a few times on these threads, the HDR alone is worth the purchase. If you have a TV and disc player capable of playing HDR, go get these discs. If not, then these discs are significant enough to warrant an upgrade to HRD equipment.
Btw, has it not been a known fact that the OT’s HDR isn’t a true HDR?
It’s interesting to note that watching these in the form of properly tone-mapped HDR -> SDR 4k video files provides some really nice images as well.
