Best Mode 4K/HDR CMS and color pre-calibration did have similar errors to those found with the Best Mode 1080p and improvements were made by calibrating the white balance, but that’s where the similarities end. While Home Cinema 3200 has a Rec2020 color space option it doesn’t mean it can cover it. Since the projector also doesn’t have the color filter found in Epson’s more expensive Home Theater projectors, it also can’t reproduce 100% of DCI-P3
The Home Cinema 3200 color gamut measured 103.5% of rec.709 and 76.3% of DCI-P3. Using the CMS adjustments, I could only improve the lower levels (20 & 40%). Any attempt at aggressive calibration resulted in making the linearity errors even worse. I could not increase 60%, 80%, or 100% saturation. I could only make improvements to their hues.
Note: adjusting the HDR Setting has an impact on CMS tracking. When adjusted the Hue stayed correct but brightness and saturation measurements were affected. I made my CMS adjustment with the HDR Setting at 5.
Overall, I the P3 color performance could have been better but after calibration, the Home Cinema 3200 still delivered a good SDR and HDR picture.
