However, the N5 was calibrated and the Epson was not, it was new and had less than 250 hours on the bulb they were waiting for the bulb to get to 250 hours and then were doing a calibration so this was out of the box blacks. Things may change in perception when the Epson gets calibrated and the brightness comes down with bulb useage and calibration. When we selected the P3 color mode, I think Cinema mode, on the Epson, JVC was about the same brightness. Too bad JVC doesn't have an equal setting with Epson for a high Lumen (3000 would be a nice minimum rec 709 setting). Then the JVC could get the ambient room crowd and the cave room crowd.
The JVCs gotta do something about their lack of lumens. I feel like we are on the cusp of a breakthrough in much higher lumens while not sacrificing black levels. Who and when is the question.
The Epson is not really brighter or much brighter than JVC.
Uncalibrated the Epson 5050 is about 1900-2000 lumens in natural or bright cinema.
Uncalibrated the JVC is about 1600-1700 lumens in all modes.
Calibrated they are within about 100 lumens of each other. The Epson drops down quite a bit as bright cinema and natural are a lot less accurate out of the box than the standard JVC modes.
Were you watching HDR or SDR? If HDR was the JVC using the 3.10 firmware frame-by-frame dynamic tone-mapping?
If it was SDR are you sure the JVC wasn't calibrated to 14 foot-lamberts as a typical SDR calibration would be? If so then they would have closed the iris down manually to bring the brightness down to the 14 fL.
I am using the JVC on a 140" 1.1 gain white screen and I use low bulb because even that is more than bright enough. Going to high bulb just raises the black floor more than is necessary and unless you have a really large screen, lots of people wont even need high bulb, or they can use it after their bulb dims a lot.
With the P3 filter, the Epson actually drops down to about 1000-1100 lumens. The NX5 doesn't have a filter, but achieves around 90% P3 natively. The NX7 has a filter though and engaging that drops the brightness down to around 1400 and is much brighter than the Epson, with 100% P3 coverage.
