The following is my opinion: I would leave out the AVR and UHD blu-ray as being critical in your display evaluation because you want to see an improvement before introducing other factors, i.e.: test the hypothesis. In fact, you should be browsing the owner threads of those displays for information on how to evaluate them and how well they are supported, just note that on the Internet it seems that more people complain than compliment, no matter which topic! :~)
Bring one display home, judge it for everything you do on your current display: broadcast or cable TV + recordings, DVDs and HD blu-rays, streaming services like Netflix, and gaming. You should see an improvement to justify the investment, otherwise return it and try the next brand because this first stage of evaluation will be the majority of your viewing until UHD becomes normal.
HDR is the second stage of evaluation of your display: because HDR-DV is so early, you can't really compare HDR-10 to HDR-DV easily. The easiest approach to evaluate HDR today is to feed your display streaming HDR-10 from Amazon or Netflix (if you have proper bandwidth from your ISP) or buy a UHD blu-ray player. If your display does HDR-DV, you can try Vudu streaming. This implicitly tests your ISP, everything is UHD, and now you should see HDR. If HDR doesn't impress you, return the display and repeat the first evaluation with the next choice: now you will be able to compare (from memory) how well the displays impress you. Our memory is fallible and you may not be calibrating the displays for proper comparison, but your impressions on how easy it is to operate the display and the overall out of the box performance should be sound.
If you are happy with the results of both stages, keep your display. Don't worry about firmware updates because they generally deal with bugs and compatibility issues, not adding new features. The only exception I know is that Vizio promised adding HDR-10 to the P series this summer and it hasn't happened yet. You would also need to add an external TV tuner for OTA to the P65 if that's important to you.
You can move onto your AVR upgrade next to insure it supports everything you've tested above and/or try adding UHD blu-ray if you find your ISP can't handle streaming UHD HDR + subscriptions without a justifiable monthly cost.
Anyhow, there are a lot of factors, I've tried to streamline the evaluation process by focusing on the display somewhat without knowing your criteria that you want addressed in future firmware.
