Did I understood correctly that in your entry level Pro is FMX panel and in your another Pro is LG or Samsung? If so maybe this FMX is not such a bad. It just does not look so much different than my Air 2018 LG display which is even not P3! In my opinion when looking at demo Air 2018 and earlier Pro 2019 and 2017 nTB models at the shops they looked so much better than Air 2018. I'm not saying I don't see any difference between my Air 2018 and entry Pro, but difference is quite small. You are sure your colorimeter is giving reliable results?
Also what factory your entry Pro is manufactured? It shows in machine serial number first letter? Mine is C (Quanta).
Answer to your questions:
- My 2019 is indeed FMX and the 2018 is LG. I actually think that this FMX is from
Japan Dispalys, but I do not have any evidence for this.
- It’s almost impossible see the difference between a high quality RGB (Air 2018 or any good quality monitor) and DCIp3 during day to day usage. To see the difference you need P3-content (a picture or video), such as this one:
- The colormeter is still very accurate, because we used it for OLED TVs and the results match the provided calibration data.
-My serial number starts with C02.
