I've only a few 4K UHD Blu-rays with Dolby Vision. Haven't noticed anything abnormal when viewed on the projector. From what I've read about the differences between the static vs dynamic rendering of the HDR, perhaps it's subtle enough as not to ruin things very much. I guess I'll find out in a few months.You will get HDR on your PJ but it will not automatically adjust black levels which is how I understand DV works.
Should look fantastic on your BIG screen.
