I must say again that for most people the M-series will give them excellent cable/Satellite video with the proper settings and excellent Blu-ray or DVD playback again with the correct settings. For most people that is enough. They never intend to buy a UHD Blu ray player or invest $30 per movie for UHD HDR streaming content. For those people keeping the M-series is the best financial decision.
However, for the people that really want to see more than just 1080p Blu rays they will have to invest in HDR. The issue is that that currently every single UHD Blu ray has the HDR10 headers. Those headers can't be read by either the 2015 M-series or the 2016 P-series currently. The difference is that the 2016 P-series will be able to read those headers in 1-2 months. The P-series is also a 10 bit TV with a much wider color gamut.
Without being a 10 bit TV you will have to do a down conversion to 8 bit at some point to display the content with the M-series. Theoretically that down conversion should be possible with minimal losses. However, my experience with the M80-C3 was that the Samsung K8500 UHD Blu ray player was doing that down conversion automatically and it never did it right. It is possible that future UHD Blu ray players will do the down conversion correctly. However, those players are many months if not a year away and there is no guarantee they will be any different.
The improper bit depth issue results in a greenish Hue on peoples faces and especially if there is anything white in the image. It was really horrible at first but it was greatly improved with a UHD Blu ray firmware update. However, it was never completely fixed. Some people might not even notice it now. It is still there though.
It was so frustrating trying to deal with the many issues of playing HDR content on the 2015 M-series that I decided to give up on the M80 and downsize to the P-series. With the P-series Dolby Vision HDR just works perfectly and there is no reason why HDR10 won't work perfectly in the near future. That peace of mind and future proofing is worth it in my opinion.
Quite honestly the color difference I see with the P-series is also worth it. So many people neglect that difference because HDR is what everyone talks about. The color difference is not subtle like the HDR difference is.
I still have my M55. It is used as a gaming only TV so there was no need to swap that out for a new P-series. However, the M80-C3 was in my dedicated theater so full HDR support was critical there.
If you find yourself with the same needs that I have in my theater room then I really do suggest selling your M-series and buying a 2016 P-series. With the new firmware it really is the best and most future proof TV on the market today.
