The filter is no longer necessary for Rec709 on the Epson 5040ub /6040ub (tw9300 for europe), this is because of the way Epson expanded the natural range of the color gamut even BEFORE the filter is engaged, hence calibrating the 5040 while maintaining lumens should be a lot easier than previous Epsons. The purpose of this filter is now VERY different than on the previous Epsons, this filter is now really solely for DCI-P3, and offers no improvement for sat tracking of rec709 (like was part of the point in the older models). So given that most of the new PJ's cannot do HDR and DCI perfectly without some hacking (other than maybe the latest JVC's), then I think it's only fair that since with external tone mapping, it should be assumed that you can still get great color WITHOUT the filter even when using HDR or modes like the DCI-P3, that is as long as you have the necessary workaround in place.
This is from my understanding of the Cine4 article... The point being, you can get good color at 1200 lumens best mode/low lamp. You just calibrate living room (or natural) instead of cinema and you have best mode lumens equivalent of the JVC. There did not appear to be any major side effects to the saturation tracking or general calibration using some of these other non-filtered modes (unlike in previous years), but that's why I asked to see other numbers from this forum to double check it.
Anyhow, even with the filter in place using Cinema mode, the mid-zoom lumens should be around 800 on low lamp best mode, about 1000 at closest throw. My conclusion is that the filter isn't even necessary for the enhanced color modes either if you use similar workarounds that people are already using with other projectors, hence the filter is really just for DCI convenience to not have to use external tone mapping (or at least not as much tone mapping), but similar options exist to maintain the higher lumens by using known workarounds.
The applicable part of the Cine4 article is as such (tricky read, very carefully):
"Let us recall briefly the results of the predecessor: in the living room mode (with slight reasons) reaches this 1600 lumen with a contrast of 7000: 1 (EH-TW7200: 1400: 1), remain perfectly calibrated (because of the necessary Cinema-Fiters ) Is only about 800 lumens, also at slightly more than 7000: 1 native contrast.
Since the TW9300 does not require a filter for the HD color space and has a little more output brightness, the brightness yield is significantly higher with perfect colors."
